Question

An alternating voltage is represented by the equation E = E0sinwt. Write down

(a) the r.m.s. value of the voltage

(b) the frequency of the voltage

(c) the phase angle of the voltage​

Answer 1

Frequency is the number of cycles that a voltage waveform repeats itself per seconds. A voltage with 0 frequency in effect is steady at a certain value which is also known as DC voltage.
