Question

An L-R-C series circuit L = 0.123 H , R = 242 Ω , and C = 7.32 μF carries an rms current of 0.445 A with a frequency of 401 Hz .

a. What is the phase angle?

b. What is the power factor for this circuit?

c. What is the impedance of the circuit?

d. What is the rms voltage of the source?

e) What is the average rate at which electrical energy is converted to thermal energy in the resistor?

f) What is the average rate at which electrical energy is dissipated (converted to other forms) in the capacitor?

g)  In the inductor?

Answer 1

Note : Average power of source = 47.9 W and average power of resistor is also 47.9 W

Through inductor and capacitor answer will be zero.

Do let me know in case of any mistake... I will rectify it asap...

Thank you....
