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?
Factors that affect the conductor Resistance. Check all that apply
It is the reciprocal of conductivity.
What is the term applied to an atom or molecule which is not electrically balanced.
Based from the table, which material has the least resistivity.
Does current alone can be fatal?
When the current increases, what happens to the area of the conductor?
Based from the table, which material has the highest conductivity.
Based from the table, which material has the highest resistivity.
It is the ratio of the kW and KVA.
When the area of the wire was cut in half, what happens to the Resistance?
When the length of the wire increases, what happens to the power capacity of the conductor?
When the length of the wire increases, what happens to the Area of the conductor?
