What is the value of current in a charging capacitive circuit if the initial current is 2A at time t=RC.(a) 0.74A(b) 1.26A(c) 3.67A(d) 2.89AI got this question in an interview for internship.This is a very interesting question from Growth and Decay topic in division Capacitance and Capacitors of Basic Electrical Engineering |

Answer» CORRECT option is (a) 0.74A The explanation is: At time t=RC, that is the time constant, we know that the value of CURRENT at that time interval is EQUAL to 37% of the INITIAL charge in the discharging circuit. Hence, I = 2*0.37 = 0.74A. |
