A generator of emf 100 V has an internal resistance of 0.04 ohm. If its terminal voltage is 95 V, then the current in the circuit is
View answer and explanation
Correct option: C
125 A
Option C (125 A) is correct because it is calculated using Ohm's law with the difference between the emf and terminal voltage.
