A circuit is a closed loop that electrons can travel in. A source of electricity, such as a battery, provides electrical energy in the circuit.  Unless the circuit is complete, that is, making a full circle back to the electrical source, no electrons will move.

I will answer in short so that u will be able to learn ......

It is best short answer ..

Electric Circuit:

An electric circuit is a closed loop through which an electric current can flow. It consists of various components such as wires, resistors, capacitors, and power sources connected together. The flow of electric current is facilitated by the movement of charged particles, typically electrons, through the circuit.

Electric Current and its Effects:

Electric current is the flow of electric charge through a conductor. It is measured in amperes (A). When a voltage source (such as a battery) is connected to a circuit, it creates an electric field that causes charged particles to move. This movement of charged particles constitutes the electric current.

The flow of electric current in a circuit can have various effects, such as:

1. Heating: When current flows through a resistor, it generates heat due to the resistance offered by the material. This heating effect is used in devices like electric heaters and toasters.

2. Magnetic effect: Electric current flowing through a conductor generates a magnetic field around it. This principle is used in electromagnets and electric motors.

3. Chemical effect: In electrolytic cells, electric current can cause chemical reactions to occur, leading to the deposition of metals or the splitting of compounds.

4. Light and sound: Electric current can be used to generate light in bulbs or LEDs and sound in speakers.

Electric circuits play a crucial role in our daily lives, powering various devices and systems. Understanding the principles of electric circuits is essential for the design, operation, and maintenance of electrical systems.
