BUT, it is all about energy. And the truth is that a .33 microfarad capacitor charged to 230 peak voltage (325 V) carries a very low energy, less than 0.02 joules. The human body can stand a 230 V fault voltage safely during the time it takes an RCD (GFI breaker) to open the circuit. The time is around 100 milliseconds.

On high voltage power lines, what is "residual power"?

In a television show, high voltage power company workers were helping an animal to safety which climbed up a tower carrying high voltage power lines. The commentator said that though the power was shutdown but still the ''residual power'' will be fatal to the rescuers and animal. If that is correct, what is residual power? How it becomes residual?

How can I quickly and safely discharge a charged capacitor (small

If you get into voltages and currents where discharge takes a second or more, or where your discharge currents will be in excess of that 1 mA for more than 1 ms, or where the energy stored exceeds a few Joules, then you should be careful: Check the current and power ratings of the components in the discharge circuit, estimate the inductance

Does a capacitor store voltage?

Taken together, the capacitance and the amount of charge to store determines the voltage. A 1 Farad capacitor charged to 1 volt will have stored 1 coulomb as would a 0.5 Farad capacitor charged to 2 volts. The difference occurs when you want to transfer this stored charge to a circuit.
