Quizplus · Accepted Answer

In an RC circuit, the current will not be in phase with the voltage due to the presence of the capacitor. Thus, the current waveform will not be identical to the voltage waveform. However, the two waveforms will be similar, and the current will lead the voltage to some extent. Therefore, both options B and C are correct. Because the amplitude and the waveform of the current will vary in the same manner as the voltage, option A is also correct. Therefore, the best choice is option D.
