Quantum mechanics

How many electrons do conductors normally have in the valence shell?

1,2 or 3 electrons

How many electrons do insulators normally have in the valence shell?

5 to 8 electrons

Magnetic lines of force are called what?

Flux

What two things determine the intensity of the magnetic field around powerlines?

The amount of electric current (amps) flowing through the lines and the distance from the conductors

What is voltage?

is electric pressure or electromotive force

What is amperage?

amperage is the measurement of the flow of electrons

What is resistance?

is the opposition to current flow in a electrical circuit

What is wattage?

is the work that is performed when voltage and amperage are combined
