Question

Average value of A.C voltage for positive half cycle is [If V₀ is its peak voltage]

An alternating current in a circuit is given by I = 20sin (100πt + 10.05π) A. The r.m.s value of current & its frequency respectively are

The peak voltage in the output of a half wave diode rectifier fed with a sinusoidal signal without filter is 10 V. The d.c. component of the output voltage is

An alternating emf E = 5.0 Sin(314t)V is applied to a circuit containing a resistor connected in series with an unknown component X. The current in the circuit is found to be I = 3.0 Sin(314t − π/3) A.
