If the phase difference between the voltage and current waveforms in a circuit element is 30°, what is the necessary condition for this to occur?

Show Answers

The voltage and current waves must share the same frequencyThe voltage and current waves must have equal maximum amplitudesThe voltage and current waves must cross zero simultaneouslyNone of the stated conditions applyNot applicable

Explanation

For a specific phase difference to exist between voltage and current waves, both must oscillate at the same frequency. Having identical peak values or zero crossings at the same time is not a required condition for a fixed phase difference.
