Question
An ideal battery would produce an extraordinarily large current if “shorted” by connecting the positive and negative terminals with a short wire of very low resistance. Real batteries do not. The current of a real battery is limited by the fact that the battery itself has resistance.
What is the resistance of a 9.0 V battery that produces a 17 A current when shorted by a wire of negligible resistance?

Answer:
Resistance,
Explanation:
Given that,
Voltage of the battery, V = 9 volts
Current produced in the circuit, I = 17 A
We need to find the resistance when shorted by a wire of negligible resistance. It is a case of Ohm’s law. The voltage is given by :
So, the resistance in the circuit is 0.529 ohms. Hence, this is the required solution.
