An inductor of resistance $Description: E:\Gate\SSC JE Electrical New Files-Done\14_Parallel-AC-Circuits_files\image038.png$ and inductance $Description: E:\Gate\SSC JE Electrical New Files-Done\14_Parallel-AC-Circuits_files\image266.png$ is in parallel with a $Description: E:\Gate\SSC JE Electrical New Files-Done\14_Parallel-AC-Circuits_files\image267.png$ capacitor. The bandwidth is

Question 3

Calculate the power factor of an AC circuit having an impedance of 16 Ohms, if a 4 A current flows through it and its average power consumption is 200 W.

Question 4

What is the rms value of the alternating voltage (in V) having a peak value of 1000 V?

Question 5

A circuit with a resistor, inductor and capacitor in series is resonant of f_o Hz. If all the component values are now doubled the new resonant frequency is:
