If an ideal battery of e.m.f. 10 V is connected with external resistance 9 Ω Ω and a wire of length 10 m and resistance 1 Ω Ω in series as shown in figure, then calculate potential gradient for potentiometric wire.
Text Solution
Verified by ExpertsThe correct answer is:
B
Current through potentiometer wire,
∴ The potential drop across potentiometer wire,
∴ Potential gradient,
