Question
After one time constant (T) in a charging RC circuit, approximately what fraction of the initial current is still flowing?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Page 21 states that 'Current drops to 1/e of initial value (about 36%)' after one time constant.
Hint
Recall the percentage related to the current decay after one time constant, as stated on page 21.
