Question

7
A resistance of 25 ohm can inductance of 0.2
Henry
and a capacitance of 50u fare connected
in
Series across 1-0 230v, 50Hz A. C supply​

Answer 1

Answer: The frequency of AC source =f=50Hz

Thus the impedance of the inductor, X  

L

​  

=ωL=(2πf)L=20πΩ

Resistance of the resistor =20Ω

Thus, the net impedance of the circuit =  

X
