When a resistor is connected by itself to an ac generator, the
average power delivered to the resistor is 6.500 W. When a
capacitor is added in series with the resistor, the power delivered
is 4.875 W. When an inductor is added in series with the resistor
(without the capacitor), the power delivered is 2.925 W. Determine
the power delivered when both the capacitor and the inductor are
added in series with the resistor?
Please solve with steps.
P1= 6.5 =V^2/R
P2=4.785 =( V^2/(R^2+Xc^2))*R
P3=2.925= (V^2/(R^2+Xl^2))*R
P4= (V^2/(R^2+Xl^2+Xc^2))*R
P4= (V^2/(R^2+Xl^2+R^2+Xc^2-R^2))*R
= (V^2/ ([ (V^2*R/P3) + (V^2*R/P2) - V^2/P1] )*R
=1/[(1/P3) + (1/P2) - (1/P1)]
=1.419 W

An ac generator has a frequency of 1180 Hz and a constant rms voltage. When a 464-Ω resistor is connected between the terminals of the generator, an average power of 0.240 W is consumed by the resistor. Then, a 0.0730-H inductor is connected in series with the resistor, and the combination is connected between the generator terminals.

A capacitor (capacitance C1) is connected across the terminals of an ac generator. Without changing the voltage or frequency of the generator, a second capacitor (capacitance C2) is added in series with the first one. As a result, the current delivered by the generator decreases by a factor of three. Suppose that the second capacitor had been added in parallel with the first one, instead of in series. By what factor would the current delivered by the generator have increased?
