Question

the phase difference between voltage and current wave through a circuit element is given as 30. The essential condition is that:<br />
1.both waves must have same frequency<br />
2.both waves must have identical peak values<br />
3.both waves must have zero value at the same time<br />
4. none

Answer 1

hey dear your answer is here...

both the wave must have same frequency

Answer 2

The answer is (1). Both waves must have same frequency.

• Phase difference is given as the difference in the phase angles of two waves.
• Voltage is the work done per unit charge, to move a test charge between two points in a circuit.
• Frequency is the number of occurences in 1 second or per unit time.
• Since the phase difference between voltage and current wave through a circuit element is 30, both the waves must have the same frequency.
