Electro Magnetic Induction And Alternating Currents Question 198
Question: In the LC circuit, the current is in the direction shown and the charges on the capacitor plates have the signs shown. At this time,
Options:
A) I is increasing and Q is increasing
B) I is increasing and Q is decreasing
C) I is decreasing and Q is increasing
D) I is decreasing and Q is decreasing
Show Answer
Answer:
Correct Answer: B
Solution:
- As it can be easily seen by the direction of I that Q is decreasing thus, energy of capacitor is decreasing and hence, energy of inductance is increasing or $ ( \frac{1}{2},LI^{2} ) $ gives that I is increasing.
