PHYSICS - Electricity - Wires

The video tutorial covers the importance of wire safety, explaining how broken wires can be dangerous. It delves into the wiring of plugs, focusing on the roles of live, neutral, and Earth wires in electrical circuits. The Earth wire is highlighted for its safety function, preventing electric shocks. The video also explains the role of fuses in preventing fires by breaking circuits when currents are too large. Additionally, it discusses the importance of insulation in wires and provides safety tips. Finally, it offers a mnemonic for remembering wire color coding and placement in plugs.

What is the primary function of wires inside a house?

• To provide internet connectivity

• To carry electricity to sockets and lights

• To support the structure of the house

• To enhance the aesthetic appeal of the house

Which wire in a plug is responsible for carrying the current into the plug?

• The blue neutral wire

• The striped wire

• The green and yellow Earth wire

• The brown live wire

What is the purpose of the Earth wire in a plug?

• To complete the circuit

• To prevent electric shocks by directing current away

• To carry the current into the plug

• To provide internet connectivity

How does a fuse prevent electrical fires?

• By redirecting the current to the Earth wire

• By insulating the wires

• By melting and breaking the circuit when the current is too large

• By cooling down the wires

What material is used for the outer insulation of wires to ensure safety?
