In the given circuit, for maximum power to be delivered to R_L, its value should be ______ Ω. (Round off to 2 decimal places.)

In the circuit, switch 'S' is in the closed position for a very long time. If the switch is opened at time t = 0, then i_L (t) in amperes, for t ≥ 0 is

For the network shown, the equivalent Thevenin voltage and Thevenin impedance as seen across terminals 'ab' is
