A battery having e.m.f.

5\,\,V

and internal resistance 0.5 Ω is connected with a resistance of

4.5\,\,\mathrm{\Omega }

then the voltage at the terminals of battery is

View answer and explanation

Correct option: A

4.5\,\,V

Option A (4.5 V) is correct because it is the terminal voltage calculated using Ohm's law and the voltage drop across the internal resistance.
