IP Tuning a Radio A radio tuning circuit contains an RLC circuit with R = 5.0 N and L = 2.5 uH. Part C Explain. Essay answers if the capacitance Submit Reqy Part D Find the impedance o FynHARE VAN

Answer 1

In a series RLC circuit,

R = 5 Ω; L = 2.5 x 10^-6 H

Part C

The impedance of a series RLC circuit is Z = {R² + (X_C – X_L)²}^1/2

The capacitive reactance, X_C = 1/2πfC . it can be seen from the equation that an increase in capacitance decreases the capacitive reactance. A decrease in capacitive reactance results a decrease in impedance of the circuit as evident from the equation for the impedance Z.

Part D

At resonance, capacitive reactance, X_C = inductive reactance, X_L

(X_C – X_L) = 0 at resonance

The impedance of a series RLC circuit is Z = {R² + (X_C – X_L)²}^1/2 = R = 5 Ω

The impedance of the circuit at resonance, Z = 5 Ω
