The expression of voltage across resistor in the circuit shown below is?

A)

V_R = 20(e^t)V

B)

V_R = 20(e^-t)V

C)

V_R = 20(-e^t)V

D)

V_R = 20(e^-t)V

Correct Answer : V_R = 20(e^-t)V

Explaination : The expression of voltage across resistor in the circuit is V_R = iR =(2(e^-t))×10=20(e^-t)V.
