JEE MainPhysics
The sinusoidal voltage of an a.c. source is given as
V = 100 sin (100πt) cos (100πt). Then
Show answer and solution
The above relation can be written as
V = 50 (2 sin (100 πt) cos (100 πt))
or V = 50 sin (200πt)
∴ V_o = 50 V
f = 100 Hz
V = 50 (2 sin (100 πt) cos (100 πt))
or V = 50 sin (200πt)
∴ V_o = 50 V
f = 100 Hz
