Q1:

Two passive elements are connected in series and a dc voltage is applied to the circuit. The time variation of the current is shown in figure. The two elements are

A one resistance and the other inductance

B both resistances

C one inductance and the other capacitance

D one resistance and the other capacitance

ANS:A - one resistance and the other inductance

In an RL circuit excited from dc source the current rises exponentially with a time constant
