An electric circuit is a system of electrical components that are connected together to allow the flow of electrical current. The major components of a circuit include:

1. Power source: This is the component that provides the electrical energy to the circuit. It could be a battery, generator, or power supply.

2. Conductors: These are materials that allow the flow of electrical current. Wires are the most common conductors used in circuits.

3. Switches: These are components that can open or close the circuit to control the flow of electrical current.

4. Resistors: These are components that resist the flow of electrical current. They are used to control the amount of current flowing through the circuit.

5. Capacitors: These are components that store electrical charge. They are used in circuits to filter out unwanted signals or to smooth out voltage fluctuations.

6. Diodes: These are components that allow the flow of electrical current in one direction only. They are used to convert AC (alternating current) to DC (direct current).

7. Transistors: These are components that can amplify or switch electronic signals. They are used in electronic devices such as radios, televisions, and computers.

Overall, the major components of a circuit work together to control the flow of electrical current and perform specific functions within the circuit.
