Changes in the gross charge can be lethal.

Re: A simple explanation of lighting, induction
and other capacitors that store and release a charge,

Why not say:

“ The net charge of a closed system is always zero,
the strength of the field is the gross charge,
and changes in the gross charge can be lethal. ” ?

Dictionary.COM says:

“ induction ( Electricity, Magnetism )

The process by which a body having electric or magnetic properties
produces magnetism, an electric charge, or an electromotive force
in a neighboring body without contact.

Compare electromagnetic induction, electrostatic induction. ”.

“ capacitor ( electronics )

An electronic device that can store electrical charge.

The charge stored Q in Coulombs is related to
the capacitance C in Farads
and the voltage V across the capacitor in Volts by ‘ Q = C * V ’.

The basis of a dynamic RAM cell is a capacitor.
They are also used for power-supply smoothing ( or ‘ decoupling ’ ).

This is especially important in digital circuits where
a digital device switching between states causes
a sudden demand for current.

Without sufficient local power supply decoupling,
this current ‘ spike ’
cannot be supplied directly from the power supply

due to the inductance of the connectors and so will cause
a sharp drop in the power supply voltage near the switching device.

This can cause other devices to malfunction
resulting in hard to trace glitches. ”.
