Correct Answer : Option (C) : RC
Explanation : The time constant of an R-C circuit is RC and it is denoted by τ and the value of τ in dc response of R-C circuit is RC sec.
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.
