Accepted Answer

Option D: 20 amps. Applying Ohm's law and superposition theorems to composite waveforms, the average load current equals the DC component divided by load resistance ($1\ \Omega$). With a DC voltage component yielding 20 volts across a 1-ohm resistor, the resulting average load current is 20 amps.
