Direct Current - a direct current (oc) flows in one direction, either steadily or in pulses.

Current refers to the quantity of electrons passing a given point.

Voltage - refers to the electrical pressure or force

Resistance - refers to a cause restriction in the flow of a current

Power - refers to the work performed by a current

Potential Difference - the difference in voltage between the two ends of a conductor through which a current flows. Also known as voltage drop.

a potential difference of 1 volt will force a current of 1 ampere through a resistance of 1 ohm, or: V = I x R or I = V / R or R = V / I

P = I x V or I^2 x R

Pages pertaining to house and automotive electrical systems

Pages about small computers, programming and process control
