The value of the resistance of the series RLC circuit attached to a 120 V/60 Hz power line is 35.57 ohms.
What is power factor of RLC series circuit?
The power factor of RLC series circuit is determined from the ratio of resistance to the total impedance of the circuit.
Pf = R/Z
0.83 = R/Z
where;
- R is the resistance of the circuit
- Z is the impedance of the circuit
Z = V/I
0.83 = R/(V / I)
0.83 = (RI) / (V)
RI = 0.83V
R = 0.83V/I
R = (0.83 x 120) / (2.8)
R = 35.57 ohms
Thus, the value of the resistance of the series RLC circuit attached to a 120 V/60 Hz power line is 35.57 ohms.
