Question : 161 of 199

Marks: +1, -0

If in an R-L-C series circuit, the frequency is below the resonant frequency, then

Solution:

At resonance

X_L = X_C

, At the frequency below resource,

X_C > X_L

Z=√{ R ^2+({X _L-X_C)^2}

X_C=1/{ 2πω c} , X_L = .2πω L

at low frequency

X_C

is higher the

X_L
