... Faraday’s Law says that you can create (induce) more voltage by 1) moving the B-field faster 2) moving it into and out of more coils of wire **the amount of current produced by electromagnetic induction depends not only on the induced voltage but the resistance of the coil and circuit to which it’s ...

How a generator works
... wires are conductive electrons that can be influenced to move either by being pushed or driven. When there is potential differences charged electrons flow. The flow creates an electric charge, but without potential difference there would be no charge. The rate in electrical flow is measured by amper ...

High voltage
The term high voltage usually means electrical energy at voltages high enough to inflict harm on living organisms. Equipment and conductors that carry high voltage warrant particular safety requirements and procedures. In certain industries, high voltage means voltage above a particular threshold (see below). High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to demonstrate arcing, for ignition, in photomultiplier tubes, and in high power amplifier vacuum tubes and other industrial and scientific applications.
