The three basic electrical quantities are:
- Voltage
- Electric Current
- Resistance
Voltage is the pressure exerted from an electric circuit’s power source that is used to push charged electrons through a conducting loop, enabling them to do work such as the illumination of light. It is measured in terms of volts and its variations.
The flow of electrons through a conducting material is known as an electric current. It is measured in terms of amperes and its subsets.
Resistance is defined as the ratio of voltage to current. It is measured in terms of ohms and its variants.
