Transmission, distribution and Conversion of electricity into other forms of energy

Power Grid

This refers to the large-scale network used to transmit electricity from power stations to various regions (homes, industries, schools, hospitals, etc.). It involves high-voltage transmission lines to ensure efficient long-distance distribution.

Electric Circuits

These are the smaller pathways that carry electric current in homes, schools, laboratories, and other places. An electric circuit consists of:

1. Source of electricity (like a battery or power supply)
2. Connecting wires (that carry the current)
3. Switches (which control the flow of electricity)
4. Electrical appliances or devices (like lamps, heaters, or motors)

Conversion of Electrical Energy

Electrical energy can be converted into different forms of energy depending on the appliance:

1. Light and Heat: In a torch, electrical energy is transformed into light and heat energy.
2. Heat: An electric heater converts electrical energy into heat energy to warm a space.
3. Sound: An electric bell changes electrical energy into sound energy, which produces a ringing noise when activated.
