In a tuned radio receiver R, L, C series circuit for resonance, the inductive and capacitive reactance XL and XC respectively are related as
XL = XC
XL = 1/2XC
XL = 1/XC
XL = 2XC
Објашњење
In an R - L - C circuit resonance occurs when the inductive reactance (XL), is equal to the capacitive reactance (XC)
1.e XL = XC
1.e XL = XC
