Vs25cos377t60oV Draw the frequencydomain equivalent circuit

Vs=25cos(377t-60^o)V

Draw the frequency-domain equivalent circuit.

What is the phasor transform

What is the frequency

What is the amplitude

Solution

IN S-DOMAIN INDUCTIVE REACTANCE XL=SL=25*10^-3S

FROM THE SOURCE VOLTAGE w=377 rad/sec

we know w=2*3.14*f

f=377/(2*3.14)= 60 hertz

from the source voltage, amplitude vm= 25 volts.
