Engineering Utilities 1 (MODULE 1 to MIDTERM) Terms only

is a form of energy generated by friction, induction or chemical change, having magnetic, Chemical and radiant effects. In short, it is Electrons in motion.

is the electrical pressure that causes the electrons to move through a conductor (wire). In other words, it is the electromotive force.

is the standard unit used in measuring the strength of an electric current, It is the amount of current flow sent by one volt through the resistance of one Ohm.

is the rate or measure of power used or consumed. It represents the equivalent heat volts and ampere consumed by lights, appliances or motors. A term commonly labelled on light bulbs or appliances, giving us an idea of what kind of circuit would be installed.

refers to the wire installations that supply current to light and convenient outlets.

is the friction or opposition to the flow of current by the wires and transformers.

is the flow or rate of flow of electric force in a conductor. It will

only flow if a circuit is formed comprising a complete loop and contains all the following required components.

Electric Current is Classified as:

The electricity flows in one direction. The flow is said to be from negative to positive. The normal source of the electricity, is the dry cell or storage battery.

The electricity constantly reverses its direction of flow. It is generated by

machine called generator.

it is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA).

is a simple static device consisting of a magnetic wire wherein the primary and secondary windings are made.

The Input side is classified as the Secondary

The Output side is classified as the Primary

When the length of the wire was cut in half, what happens to the Resistance?
