What is the formula for Capacitance储能Calculate器?

Core formula: E = ½·C·V² = ½·Q·V ｜ Q = C·V. The tool returns results instantly using this formula and the selected parameters.

What engineering notes should I keep in mind when using Capacitance储能Calculate器?

储能andVoltage平方成正比，高压储能密度远高于低压。放电current很大时可瞬时输出高Power（如闪光灯、电磁炮、脉冲supply）。实际可用Energy受Capacitance耐压andEquivalentSeriesResistance（ESR）限制。
