Electronics Information

Current is the flow of electric charge, measured in amperes (amps, A).

Voltage is the electrical potential difference (electromotive force) that pushes current, measured in volts (V).

Resistance opposes the flow of current, measured in ohms (Ω).

Power is the rate of doing electrical work, measured in watts (W).

Electric charge is a fundamental property of matter; like charges repel and opposite charges attract. Its unit is the coulomb.

A conductor is a material that allows electric current to flow easily, such as copper, silver, gold, and aluminum.
