Question

1)An RLC series circuit is in resonance at 30 kHz. If it has a 400 ? resistance, a 2.5 mH inductor, and a capacitor,what is the capacitive reactance

In a series LRC circuit the rms voltage across the resistor is 80.0 V, across the capacitor is 120 V, and across the inductor is 60.0 V. If 1.50 A rms is flowing in this circuit, what is the average power dissipated? An incident ray makes an angle of 30 degree with the horizontal in air as it hits a piece of glass with an index of refraction n glass = 1. 52. Calculate the angle theta

Explanation / Answer

The average power is the effective
power dissipated by the resistor:
P_ave = VR_rms*i_rms = 120 W

The other data is not needed but:
a=0.643501108793281 rad
P_ave = E_rms*i_rms*cos(a) = 120 W
where cos(a) is the power factor.
and E_rms is the effective vector voltage.
