Question
If the resistance R in an RCL series circuit is doubled, by what factor does the resonant frequency change?
The resonant frequency increases by a factor of , because it is proportional to the square root of the resistance. If the resistance R in an RCL series circuit is doubled, by what factor does the resonant frequency change? The resonant frequency increases by a factor of , because it is proportional to the square root of the resistance. The resonant frequency doubles, because it is directly proportional to the resistance. The resonant frequency does not change, because it does not depend on the resistance. The resonant frequency decreases by a factor of , because it is inversely proportional to the square root of the resistance. The resonant frequency decreases by a factor of 2, because it is inversely proportional to the resistance.
Explanation / Answer
The resonant frequency does not change, because it does not depend on the resistance
