There is no way to answer the question. You would also need the equivalent resistance of the motor.
12 volt batteries are used in many cars. A car with a small engine will have a relatively small starter motor and may use less than 200 amps. A car with a larger engine may need a battery which is still 12 volt but provide 700 amps.
V = I x R or I = V / R .... So if you know the resistance, R, then you divide to find the current, I.

Synchro motor and its function?
A Synchro Motor is a Elecrical motor consition out of a single-phase Inner/Rotor windings, and a Three-phase Outer/Stator windings. The Outer/Stator windings are connected Electricly in a Star formation. ... ie: The inner ends of each the three windings are connected to one another. And the outher ends will then be connected to another Synchro Motors outer ends. The Inner/Rotor windings are connected to a single-phase AC power supply. The Rotor Windings in turn transfer energy over to the Outer/Stator windings. The Stator Windings are 120 degrees appart. And therefore depending on the Rotation of the Inner/Rotor Windings the Outer/Stator Winding get a different magnatude of magnetic flux, transferring a different amout of current flow to each of the three Outer/Sator windings. That bring us to the use of a Synchro Motor: ... A Syncrhro Motor works in pairs of 2 or 3, and are used to transfer rotational oriantation from one Synchro motor to another. Depending on how the Synchro Motors are connected to one another you can mirror the rotation from the first motor to the second. For standard Synchronigation you would connect The 3 Outer/Stator windings as such (1-1) (2-2) & (3-3). To mirror the Rotation you could connect (1-2) (2-1) & (3-3). Remember I said you could have 3 Synchro motors... The Third is wired differently inside... it has 3 Inner/Rotor windings & 3 Outer/Stator windings. The Rotor & Stator winding are connected in a star formation. The third Synchromotor bring about a difference in rotation. You could add or subtract rotational oreantions. A = Synchro Motor 1 ...B = Synchro Motor 2 (with 3 Stator & 3 Rotor windings) ...C = Synchro Motor 3 A+B=C Or A-B=C Synchro motors are used in ships, for opening & clossing valves from the bridge to for instance the Engine room. A more advanced system of the synchro technology integrates with a Servo Motor, that in turn can controls the rudder of the ship. Other uses are in Analoge computers & Electronic Weapon Guidence Systems.
What formula would you use for current?
=sum(current/4*)
What does an angle sign look like?
It would look kind of like this /_ but it would be connected.
How much voltage does four 4 5v batteries have when in sequence eg positive wire to negative back up to positive and so on Does it add up to 18 volts total or it remain at 4 5volts?
That type of arrangement is known as a "series" combination. Its schematic diagram looks like this: ----ⱶ|-ⱶ|-ⱶ|-ⱶ|--- The voltage between its ends is the sum of the voltage of the individual cells. If each unit is nominally a 4.5V battery, then the end-to-end voltage is nominally 18 volts, but it can only supply as much current (amps) as any single one of them can. If all 4 positive ends were connected together, and all 4 negative ends connected together, then you'd have a "parallel" combination. The nominal output voltage would still be 4.5 volts, but it could supply 4 times as much current (amps) as a single one of them can.
How old would you be if you were born in 1965?
As of December 2011, you would be 46 years old. Current Age = Current Year - Year of Birth, if the person has had a birthday in the current year and one year less than that if not.
Where is the starter motor?
Year, make, model and engine size would help but if you follow the positive battery cable from the battery to the other end of it, it will be connected to the starter.

What is the phase current of a three phase 2.2kw 415v motor connected in star?
The line current would be the same if the motor were connected in delta. The current can be based on the rule of thumb which says 7 amps must be allowed for a 1-HP single-phase motor on 240 v. A 2.2 kW motor is three times as powerful, and on a three-phase supply of the same voltage (240/415) it would draw 7 amps.
What would be the result if two batteries are connected in series in terms of power and voltage and current?
If two identical batteries were connected in series, the resulting voltage would double, the available current would remain the same, and the available power would double. Note that, by Ohm's Law and the Power Law, doubling the voltage into a set resistance would double the current and quadruple the power. This is inconsistent with the battery's ability to provide a certain current, so you would also need to double the load resistance, otherwise you could damage the battery.
Why starting current of the motor is high when it is directly connected to supply voltage?
When a motor is stationary, it is not generating a back-mmf which would otherwise act to oppose the applied voltage and, thus, reduce the supply current. However, as the motor runs up to speed, it generates an increasing back-emf, and the supply current falls.
A 3.6 volt Li-ion battery is connected to a circuit that has a resistance of 2k Ω. How much current would flow?
as i=v/R then i =1.8mA
How do you make a toy car have a motor 2 1.5 volt battery and a switch need to make it as fast as possible someone please tell us how to connect the battery motor and switch and strategies?
I would suggest that you connect all components in series. That is, + of the first battery to - of the second. + of that battery to the switch and the second terminal of the switch to the motor. The last wire from the motor back to the - of the first battery. To reverse direction of the motor just swap the leads. There are many factors that will also affect speed such as how the motor is connected to the wheels, type of bearings, even the width and diameter of the wheels. Good luck and have fun!
Can you charge car battery using 110V AC outlet?
Only if you have a battery charger connected to that 110 volt AC outlet. If you are thinking about connecting live AC current directly to the battery post forget it. That would more than likely cause the battery to explode.
How is alternative current prodused in a battery?
A battery by itself will only supply DC output. You would need a method to convert DC to AC, such as an inverter, in simplified terms: an electronic circuit which has an oscillator to create the desired frequency then amplifies it to the desired magnitude output. Another way, which I don't know if used anymore, is a motor-generator set. A DC motor's shaft is connected to an AC generator's shaft, and the output is taken from the AC generator.
What battery would I use to run a 12V DC fan motor that has an input current of 6 amps?
That's a large amount of current for a battery to use. You may want to purchase a 12V marine battery or 12V deep-cycle car battery. Or you can use a car battery charger with a 6amp minimum output. The amperage rating for your motor is a minimum requirement. For your power source, use the highest amperage rating you can find. Whether you use a 10 amp battery or a 10 million amp battery, it [the motor] will only draw 6 amps. The voltage is a different story. Use only 12 volts DC.
When an ammeter is connected in a circuit which terminal of the battery must be connected to the positive terminal of the ammeter?
The positive terminal of the battery would be connected to the positive terminal of the ammeter. The load would then be connected between the two negative terminals, positive side of the load being connected to the negative side of the ammeter.
Can 12 volt battery can be conected to three 12 volts dc motor?
Yes if the battery can deliver enough current for enough time to be useful. You would connect the motors in parallel. If for example each motor required 1 amp and you had a 30 aHr (amp hour) battery the motors could run for about 10 hours.
