Answer:
At resonance impedance of series RLC circuit is minimum and equal to resistance of the circuit
Explanation:
Let the resistance of the series RLC circuit is R
Capacitive reactance of the circuit is and inductive reactance of the circuit is
We know that impedance of the series RLC circuit is given by , here R is the resistance is inductive reactance and is capacitive reactance
At resonance capacitive reactance will be equal to inductive reactance
So
So impedance will become
So from above calculation we can say that impedance of series RLC circuit is minimum and equal to resistance of the circuit
The first one is Force & the second one Power.
