Passive components

Electronic components that consume/absorb energy but do not produce energy.

Active components

Components that rely on a power source and can inject power into a circuit, such as transistors.

Resistance

The property of a resistor to oppose current flow, measured in ohms (Ω).

Capacitance

The property of a capacitor to store charge, measured in Farads (F).
