Correct Answer : Option (B) : decays with time
Explanation : In a R-C circuit, when the switch is closed, the response decays with time that is the response V/R decreases with increase in time.
Correct Answer : 4.6 mA
Correct Answer : True
Correct Answer : VR = 20(e-t)V
Explaination : The expression of voltage across resistor in the circuit is VR = iR =(2(e-t))×10=20(e-t)V.
