Question
1.) If the power factor for a series RLC circuit is 1.00, what is the phase constant?
2.) In an ac circuit, the current in a capacitor
leads the voltage by 90°.
lags the voltage by 90°.
is in phase with the voltage.
leads the voltage by radians.
lags the voltage by radians.
3.) As frequency is varied in an RLC series circuit, resonance is reached when
the impedance becomes zero.
the inductive reactance is equal to the capacitive reactance.
the inductive reactance is equal to the resistance.
the capacitive reactance is equal to the resistance.
the sum of the inductive and capacitive reactances is equal to the resistance.
leads the voltage by 90°.
lags the voltage by 90°.
is in phase with the voltage.
leads the voltage by radians.
lags the voltage by radians.
Explanation / Answer
here,
power factor = 1
let the phase constant be k
cos(k) = power factor
k = 0 degree
the phase constant is 0 degree
2)
the current in the capacitor leads the voltage by 90 degree
3)
As frequency is varied in an RLC series circuit, resonance is reached when
the inductive reactance is equal to the capacitive reactance
