Current
The rate of flow of charge, symbolized as I.
Ampere
The unit of current.
Ammeter
An apparatus used to measure current.
Voltage
The electric potential difference, symbolized as V.
Volts
The unit of voltage.
Resistance
The opposition to current, symbolized as R.
Ohm
The unit of resistance.
Voltmeter
An apparatus used to measure voltage.
Potential Difference
The amount of energy required to carry charge between two points in a circuit.
Electromotive Force (EMF)
The amount of energy required to carry charge around the entire circuit, supplied by a source.
Factors Affecting Resistance
Temperature, length, and thickness of the conductor.
Series Circuit
A circuit where the current stays the same and the voltage splits.
Parallel Circuit
A circuit where the current splits and the voltage remains the same throughout.
Total Voltage in Series
The total voltage is equal to V1 plus V2.
Total Resistance in Series
The total resistance is equal to R1 plus R2.
Total Resistance in Parallel
Calculated using the formula 1/Total Resistance = 1/R1 + 1/R2.
