Electro Magnetic Induction And Alternating Currents Question 347

Question: The network is a part of a complete circuit. If at a certain instant the current i is 5 A and is decreasing at the rate of $ 10^{3}A/s $ then $ V_{A}-V_{B} $ is

Options:

A) 5 V

B) 10 V

C) 15 V

D) 20 V

Show Answer

Answer:

Correct Answer: C

Solution:

By using Kirchoff’s voltage law $ V_{A}-i\ R+E-L\frac{di}{dt}=V_{B}\Rightarrow V_{B}-V_{A}=15\ volt. $
