Definition
Circuits are pathways that allow the flow of electric current. They consist of components such as resistors, capacitors, and inductors connected by conductive wires.

Voltage: Voltage is the electrical potential difference between two points in a circuit. It determines the force that drives electric charges through the circuit.
Resistance is the opposition to the flow of electric current in a circuit. It is measured in ohms and can be thought of as an obstacle that restricts the flow of electrons.
Capacitance is the ability of a component to store electrical energy in an electric field. It is measured in farads and determines how much charge can be stored for a given voltage.
