i don't really want an explicit answer but would really appreciate help with the general idea of how this could be done. we haven't covered this but it's on the hw.

In an AC circuit, the voltage across the resistor can exceed that of the voltage source. Remember that the AC voltage near resonance can be very high with respect to the source voltage. If you have the resistor connected parallel to a reactive element, the voltage across it can be higher than the source voltage or the allowed voltage.

Try a circuit with an inductor in series with the resistor connected parallel with a capacitor. Find the condition needed that the power of the circuit exceed the nominal power rating of the resistor.

As an example, determine the power when the angular frequency of the 15 V source is ω=1000 1/s and a 2 μF capacitor is connected parallel to the 1kΩ resistor, and they together are in series with a 0.5 H inductor.
