This heat dissipation in the lattice, called Joule heating, is the source of power dissipation in a resistor. Note that while inter-electron collisions may yield their own associated thermal energy of motion, this energy stays internal to the system until it is dissipated into the metallic lattice, which does not carry the current.

You cannot directly convert capacitance (measured in farads) to joules. Capacitance is a property of a capacitor, while joules represent energy. The energy stored in a capacitor is calculated using the formula: Energy (Joules) = 0.5 * Capacitance (Farads) * Voltage^2 (Volts) How do you calculate capacitance from energy?
The energy stored in a 1-farad capacitor with a voltage of 1 volt is approximately 0.5 joules. How much power is a 1 farad capacitor? A 1-farad capacitor does not inherently have a power rating. Capacitors store energy, but their power handling capacity depends on the voltage and current they are subjected to in a given circuit.

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 capacitors as well as the voltage …

When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.
