Power = E2 / R
Resistance = E2 / power = (240)2 / 3,000 = 19.2 ohms
Current = E / R = 240 / 19.2 = 12.5 amperes

The Storage battery of a car has an emf of 12 volt if the internal resistance of the battery is 0.4 resistance what is the maximum current that can be drawn from the battery?
You have to imagine the internal resistance as being in parallel with any load you connect. You get the maximum possible current when the load is zero. In this case, just apply Ohm's Law. That is, divide the voltage by the internal resistance.
What is the current being drawn by a 100W light bulb and what is the resistance of a 100W light bulb?
Assume the rating of 100W refers to operation on a supply of 117 volts.Power = (voltage) x (current)Current = (power) / (voltage) = 100/117 = 0.855 ampere (rounded)Power = (voltage)2 / (resistance)Resistance = (voltage)2 / (power) = (117)2 / 100 = 136.89 ohms
How does electric resistance relate to energy transformation?
Power in a circuit is inversely proportional to the resistance, all other things being equal. Voltage equals amperes time resistances, so amperes equals voltage divided by resistance. Watts equals voltage times amperes, so watts equals voltage squared divided by resistance.
The current load of a trnsformer is the current drawn by the?
Load!
How can you calculate current drawn in 60 HZ circuit?
You need to divide the supply voltage by the impedance of the load. The impedance of the load is the vectorial sum of its resistance and reactance, where reactance is proportional to frequency.
Does increasing the voltage to an electric heater increase the amperage it draws?
Yes, increasing the voltage to an electric heater will typically result in an increase in the amperage it draws. This is due to Ohm's Law, which states that current (amperage) is directly proportional to voltage and inversely proportional to resistance. As voltage increases, the current drawn by the heater will also increase.
Why terminal potential difference is decrease when current in the circuit is increased?
If the terminal voltage decreases when more current is drawn, that is due to the internal resistance of the power supply. Every power supply has a limit to how much current can be drawn. It is limited by the internal resistance and due to ohms law the more current drawn through a resistor, then the more voltage is produced across it. This is in opposition to the terminal voltage and is subtracted from it.
Explain why an electric bulb becomes dim when an electric heater in parallel circuit is made onWhy dimness decreases after some time?
this happen due to sudden amount of voltage drop in the main feeder due to large current drawn by the heater , so this drop in voltage will let the bulb operate by avltage of a mount (V-Vd) [where V represent the supply voltage and Vd represent the voltage drop in the main feeder of the circuit] , which is less than the voltage before the heater is connected and due to this situation the current passes through the wire of the bulb will be less and therefore the brightness of the bulb becomes dim.after a while the wire of the heater will has high temperature which increase its resistance and due to this the current drawn by the heater will decrease than the current at the first time , therefore the drop in voltage will also decrease , which implise increase in current drawn by the bulb and therefore the dimness decrease .
How does internal resistance affect operation of a cell or battery?
It causes the battery's voltage to drop when a current is drawn from it.
What does the slope of voltage-current curve represent?
It depends. If voltage is drawn along the horizontal axis, then the slope at any point on the graph represents the reciprocal of resistance at that point. If current is drawn along the horizontal axis, then the slope at any point on the graph represents the resistance at that point.
If you doubled the load resistor in a wheatstone bridge. the load current would not be half as much Why not?
Because by increasing the load resistance, the total circuit resistance is reduced. This means with less resistance, there is more current drawn from the source. Doubling the size of a load resistor increases the load current.
An old television draws about 3 A of current It plugs into a wall outlet that is 120 V What is the resistance in ohms of the television?
Is this, intentionally, a trick question?We are dealing with alternating current, here, not direct current. So, if you divide the supply voltage by the current drawn by the television set, you are determining its impedance(Z), not its resistance:Z = V/I = 120/3 = 40 ohmsImpedance is the vector sum of resistance and reactance. As the current is probably being drawn by a transformer, the resistance will be significantly lower than the reactance, perhaps only an ohm or two -if that!So, from the information supplied, you cannot determine the resistance.
What is the condition for maximum current that can be drawn from a cell?
The maximum current that a cell can deliver flows when the resistance between the terminals of the cell is zero. This situation occurs when the terminals are connected by a conductor with very low resistance, such as a thick wire or a wrench. But not for long.
Will 208 volt single phase equipment work on 240 single phase?
No, lower voltage equipment will not operate on a higher voltage because the wattage or current drawn by the equipment will be higher that the rating of the equipment at the lower voltage. For example if you take a heater rated at 5000 watts at 208 volts, the current is I = W/E 5000/208 = 24 amps. The resistance of this heater is R = W/I (squared) = 5000/24 x 24 (576) = 8.6 ohms. Applying 240 volts to this heater whose resistance is 8.6 ohms results in this new heater wattage rating. W = E (squared)/R = 240 x 240 (57600)/8.6 = 6697 watts. As you can see the original wattage of the heater is overloaded by about 25% of what the manufacturers specified the wattage to be. Ohms law states that the current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. W = watts, I = amperage, R = resistance in ohms and E = voltage.

What are the symptoms of a loose battery terminal?
A loose battery terminal will cause intermittent power supply, high resistance and heating. A high resistance will cause a voltage drop, as more current is drawn from it.
What dose in parallel mean?
parallel means they will never cross each other. take a example when a resistance connected in parallel then a current flowing through it(both resistance) is not same depended on the value of each resistance. while in the series circuit current values is same for both resistance. parallel lines are drawn below:- series lines:- -------
