1800-102-2727A closed-loop or path of electrical components is called an electrical circuit. In an electrical circuit, the flow of electrons takes place. An electrical circuit comprises wires, a battery, switch, and other components to measure the current flowing. The source is where the electrical current starts to flow—the point where electrons or the current ends is known as a return.
Take an electric bulb, wire, electrical tape, and a battery. Connect all of them tightly and adequately. Notice what happens. When the circuit is complete, electrons flow from the battery to the bulb, generating an electrical current due to which the bulb lights up. This will happen only when the circuit is complete. If the circuit is not complete, the bulb will not glow.
In an electrical circuit, there must be a close loop and a positive-negative end for current flow. The current flow may be from positive to negative and vice versa, depending upon the type of electrical circuit.
Faulty electrical circuits may cause fire and damage to property and lives. One must not neglect any sparking or short-circuiting in the electrical circuit. Electrical appliances must be handled with care. Appliances with chemicals inside them must be taken extra care of. They may leak and cause more damage than short-circuiting or failure in electrical circuits.
The following symbols are used to denote components in an electrical circuit.
A circuit that comprises only a power supply source, switch, load, and conductor is known as a simple circuit.

1. Use good quality electrical components with proper insulation, thickness, and functioning. Install every component properly and make sure they have good quality.
2. The connections must be made tight and insulated completely to prevent any shock.
3. Switch off the main power supply before repairing or doing any electrical work in the house.
4. In a short circuit, switch off the main power supply to prevent further damage to any other appliance. Do not touch any appliance in case short-circuit occurs.
5. Do not touch any appliance with wet hands as wet hands increase conductive power, leading to shock or death.
6. Install earthing to prevent any appliance from damage and fluctuations.
