Just use Ohm's Law
Voltage = Current x Resistance
Amps = Voltage Divided By Resistance
Amps = 120 / 260

What will be the amps of a 12v 2amp circuit if there is a 12ohm resistor on it?
The formula you are looking for is I = E/R. Amps = Volts/Resistance. If you say it is normally a 2 Amp circuit, it normally draws 2 amps. Therefore the original resistance offered to the 12v battery is 2/12 = 6 Ohms. If you then connect a 12 Ohm resistor in series, they are added, so R = 18 Ohms. Now if you put 12v across this circuit it will draw 12/18 = 0.66 Amps. Or If you just put a 12 Ohm resistor across the 12v supply it will draw 1 Amp. If the circuit is protected by a 2 Amp fuse, it will not blow, but the resistor will get hot.
A series circuit has individual resistor values of 200 ohms 86 ohms 91 ohms 180 ohms and 150 ohms What is the total resistance of the circuit?
In a series circuits, you simply add the the values of each resistor and that is you answer. i.e. - 200 + 86 + 91 + 180 + 150 = 707 ohms
If there is a potential difference of 12 V across a resistor with 0.25 A current in it the resistance if the resistor is?
Resistance (Ohms) = Potential Difference (Volts) / Current (Amps) So, 12/0.25 = 48 Ohms.
Two resistors are connected to a 9 volt battery the larger one provides twice as many ohms as the small one the current through the circuit is 3 amps what is resistance of larger resistor?
If the two resistors are in series, then the larger one is 2 ohms.(The smaller one is 1 ohm. Their combined series total is 3 ohms. 9/3 = 3 amps.)If the two resistors are in parallel, then the larger one is 9 ohms.(The smaller one is 4.5 ohms. The combined parallel total is 3 ohms. 9/3 = 3 amps.)
What is the function of 240 ohms resistor?
To provide 240 ohms of resistance. What those 240 ohms do in an actual circuit depends on the intention of the designer.
If voltage is 12 volts and ohms is 0.5 how many amps in circuit?
Ohm's law: Volts = Amps * Ohms, or Amps = Volts / Ohms 12 volts / 0.5 ohms = 24 amps

In a parallel circuit the smallest resistor is 500 ohms. What is the largest value this parallel circuit can have?
500 ohms.
How do you find resistance when you have current and resistance total?
If you are looking for the resistance of each resistor in either a series circuit or a parallel circuit you must measure the current I and the voltage V for each resistor. Then calculate its resistance using Ohms Law R = V / I where I = current (Amps), V = voltage (Volts) and R= resistance (Ohms).
How do you determine shorted resistor?
A short circuit is an unexpected path of zero resistance between two nodes in a circuit. If you measure the resistance of a resistor, and find that is has zero ohms, but the resistor is supposed to be somthing else, such as 100 ohms, then you can conclude that the resistor is shorted. Keep in mind that the precision of the measurement might be critical. If the resistor is supposed to be 100 ohms, but you get zero ohms, then the answer is easy. If the resistor is 0.001 ohms, but you get zero ohms, then you have to consider the precision of the measurement, the resistance of the wires, etc.
Is resistance in a series circuit equal to the largest resistor in the series?
No. The resistance in a series circuit is all the resistor values added together. eg. If two resistors were in a circuit, one was 10 ohms and the other was 30 ohms, the resistance in the circuit would be 30 ohms. Hope this helps!

Two resistors are connected in series to a 9 volt battery. The larger resistor provides twice as many ohms resistance as the smaller one. The current through the circuit is 3 amps. What is the resista?

Is resistor measured in amps?
No, a resistor isn't measured at all. A resistor has a quality called "resistance" - and that value is measured. Resistance is measured in Ohms.
