If the conductance and capacitance are both doubled in L-C - R circuit, the resonant frequency of the circuit will
Options
- Adecrease to one-half the original value
- Bdecrease to one-fourth the original value
- Cincrease to twice the original value
- Ddecrease to twice the original value
Correct answer
A. decrease to one-half the original value
Step-by-step solution
The resonant frequency v₀= 1 2 L C v₀ 1 L C If conductance and capacitance both are doubled, then v₀= 1 2 ( 1 2 L C ) So, the resonant frequency will decrease to one-half of the original value.
