Voltage, Current & Resistance

In electronics we are dealing with voltage, current and resistance in circuits.


Voltage is the electrical force, that causes current to flow in a circuit. It is measured in VOLTS .

Electrical Current

Current is the movement of electrical charge - the flow of electrons other charged particles through the electronic circuit. The direction of a current is opposite to electrons flow direction. Current is measured in AMPERES (AMPS, A ).


Resistance causes an opposition to the flow of electricity in a circuit. It is used to control the amount of voltage and/or amperage in a circuit. It is measured in OHMS.
