circuit analysis
An ideal capacitor has no resistance and therefore no heat will be dissipated by the capacitors in your circuit. The only place in that circuit (assuming all ideal parts) that electrical energy will be converted to heat is the resistor, so what you need to find is the power dissipated by the resistor, which involves the charges stored in the …
