Question

A battery of emf 3volts and internal resistance of 0.02 ohm has to supply current to resistance of 5 ohm. Find the current.

Answer 1

Answer:In such cases the internal resistance can be considered to be connected in series with the main resistance.

So, the net resistance is 5.02ohm

Now EMF is 3V

So, i = V/R = 3/5.02 = 0.597 A
