Power dissipated by an RLC circuit in the US and in Europe?

Question

An AC voltage with an amplitude of 115 V is applied to a series combination of a 162 mF capacitor, a 106 mH inductor, and a 25.0 Ohm resistor. Calculate the power dissipated by the circuit at a frequency of 60.0 Hz.

Any idea about what to do?

Answer 1

Yes.  Calculate the reactance of the capacitor and inductor.  They will be of opposite signs, and will partially cancel each others' effects.  Then calculate the total impedance of the circuit (reactance + resistance, combine like two sides of rectangle and determine the hypotenuse for the impedance.)

Given the impedance, you can determine the current and thus the power dissipated by the resistor.

Changing the frequency changes the reactances, and the net impedance.  (Europe uses 50 Hz power).  Do the calculation again.

Look up definitions for any words I used you don't understand in something like your textbook or wikipedia.

Good luck.
