Q1:

A diode is operating in forward region and the forward voltage and current are v = 3 + 0.3 sin ωt (volts) and i = 5 + 0.2 sin ωt (mA). The average power dissipated is

A 15 mW

B about 15 mW

C 1.5 mW

D about 1.5 mW

ANS:B - about 15 mW

The contribution of sine terms to power dissipation is zero.
