A resistor connected in series is a type of electrical circuit in which multiple resistors are connected one after another in a single wire, so that the electric current passes through each resistor individually.

A resistor connected in parallel is a type of electrical circuit in which multiple resistors are connected in parallel between the same two points. In such a circuit, each resistor has the same electric potential difference across its terminals, but the electric current is divided among the resistors based on their resistance values.
