Spread the loveA resistor is a passive electronic component that controls the flow of current in a circuit. It has a fixed resistance that limits the current flow and protects other components from ...

Resistors (Ω) oppose current, are color-coded, and connect in series (Rt = ΣR) or parallel. Current-limiting resistors protect LEDs.

Resistors in parallel Current When resistors are connected in parallel, the current from the power supply is equal to the sum of the currents through each branch of the circuit.
