A storage battery of a car has an e.m.f. of 12V. If the internal resistance of the battery is 0.4 ohms what is the maximum current that can be drawn from the battery?

The storage battery of a car has an emf of 12V. If the internal resistance of the battery is 0.4Omega ,what is the maximum current that can be drawn from the battery?

A 50V battery is connected across 10 ohm resistor and a current of 4.5A flows. The internal resistance of the battery is

If the combination is connected to a battery of emf 20V and negligible internal resistance,determine the current throgh each resistor and the total current drawn from. the battery

A battery of e.m.f. 10V and internal resistance 3W is connected to a resistor. If the current in the circuit is 0.5A, what is the resistance of the resistor? What is the terminal voltage of the battery when the circuit is closed?
