A circuit consists of a resistor,an inductor and a capacitor connected in series
A circuit consists of a resistor,an inductor and a capacitor connected in series. If the resistance of a resistor is \( 25 \Omega \) and the value of inductive reactance is equal to capacitive reactance, then the net impedance of the circuit will be :
- A. \( 5 \Omega \)
- B. 25\Omega
- C. \( 125 \Omega \)
- D. \( 625 \Omega \)
Step-by-step solution
In a series LCR circuit, impedance Z = √(R² + (XL - XC)²). Given XL = XC, so Z = √(R²) = R = 25 Ω.
