Solution:
Given, L = 1H, C = 1F, R = 20Ω and V = 10V.
Resonance frequency (ω0) is given by:
ω0 = 1/√LC
= 1/√1×1
= 1 rad/sec
Impedance of the circuit (Z) at resonance is given by:
Z = R
= 20Ω
Current through the circuit (I) is given by:
I = V/Z
= 10/20
= 0.5 A
Voltage across the inductor (VL) is given by:
VL = IωL
= 0.5×1×1
= 0.5 V
Therefore, the voltage across the inductor at resonance is 0.5 V or 500 mV.
Answer: (1) 500 V
Explanation:
At resonance, the inductive reactance and capacitive reactance cancel each other out, leaving only the resistance in the circuit. This results in a maximum current flow through the circuit, and the voltage across the inductor is also maximum at resonance. In this case, the voltage across the inductor is 500 mV or 0.5 V.
