conductor - any material with low resistivity; (metals, plasma, etc.).
semiconductor - a material with intermediate resistivity, (with a negative temperature coefficient of resistivity).
dielectric (insulator) - a material that does not have free charge carriers; (ceramics, plastics, etc.).
| The conductor was replaced with a semiconductor surrounded by a dielectric. |
resistor - any component that offers resistance to the flow of electric current.
resistance - defined as the ration of the voltage across a resistor over the current flowing through it.
Ohm - the unit of resistance in Volts per Amp.
| The resistor was found to have a measured resistance of one Ohm. |
conductor - any component that allows the passage of current.
conductance - the ration current over voltage across a conductor.
mho - the unit of conductance - the reciprocal of resistance.
| The conductor was found to have a measured conductance of one mho. |
resistivity - the resistance between opposite faces of a cube of material a meter on a side, in Ohm Meters.
conductivity - the reciprocal of resistivity.
| Conductivity is the reciprocal of resistivity. |
voltage - energy per charge in Joules per Coulomb.
Volt - the unit of voltage.
| The voltage across the light bulb was found to be Volt. |
current - a flow of charge
Coulomb - a charge which passes per second in a current of one Ampere.
Ampere - the unit id electric current.
| The current was one Ampere (Amp); ie. a flow of one Coulomb per second.. |
power supply - a device that supplies electric current and acts as a voltage source.
cell - a device that generates a voltage (usually by a chemical reaction between two components).
battery - a collection of cells.
| The power supply was a battery made up of three dry cells. |
power - the energy per second in Joules per second or Volt Amperes.
Watt - the unit of power
| Twenty Watts of electrical power were dissipated due to heating in the resistor. |
capacitor - a device that stores electric charge.
capacitance - the ability to store charge in Coulombs per Volt.
Farad - the unit of capacitance in Coulombs per Volt.
| The capacitor was found to have a measured capacitance of one Farad. |
