The phase difference between voltage and current wave through a circuit element is given as 30°. The essential condition is that
Correct answer: A. both waves must have same frequency
- A. both waves must have same frequency
- B. both waves must have identical peak values
- C. both waves must have zero value at the same time
- D. none of the aboveGet Study Guides
Explanation
A fixed phase difference between two steady sinusoidal waves is meaningful only when they have the same frequency; otherwise their relative phase continually changes. Equal peak values and simultaneous zero crossings are not essential.
