Question

The phase difference between current and voltage in an ac circuit is radian if the frequency of AC is $50$ Hz. then the phase difference is equivalent to the time difference of.

Answer 1

Phasedifference$=\frac{\pi }{4}radian$

Frequency$f=50Hz$

Timedifference$\Delta t=\frac{\pi }{2\pi f}=\frac{\pi }{4\ast 2\pi \ast 50}=\frac{1}{400}=0.0025s=2.5ms$
