Formula and method
Convert µF to F by multiplying by 10⁻⁶. Energy E = ½CV² and charge magnitude Q = C|V|.
Worked example
A 1,000 µF capacitor at 12 V stores 0.072 J in the ideal model and has charge magnitude 0.012 C.

Ideal constant-capacitance model. It does not account for leakage, equivalent series resistance, dielectric behavior or voltage ratings.
How this was calculated
Convert microfarads to farads by multiplying by 10⁻⁶.
Stored energy E = ½CV²; charge magnitude Q = C|V|.
Frequently asked questions
Does it account for leakage or resistance?
No. It assumes constant ideal capacitance. Leakage, equivalent series resistance, dielectric effects and voltage ratings require separate consideration.
