Understanding Torch

Which material is commonly used as a conductor inside a torch to allow electricity to flow?

• Plastic

• Rubber

• Copper

• Wood

Why is the outer casing of a torch often made of plastic or rubber?

• To help the torch conduct electricity

• To prevent the torch from overheating

• To act as an insulator, keeping electricity safely inside

• To make the torch heavier

What would happen if the wires inside the torch were made from an insulating material like rubber instead of metal?

• The torch would be brighter

• The torch would not work

• The torch would get hotter

• The torch would use less energy

Which of the following materials would be a poor choice for the internal wiring of a torch?

• Aluminum

• Steel

• Rubber

• Copper

What is the main purpose of using insulating materials in the construction of a torch?

• To increase the brightness

• To prevent electricity from escaping the circuit

• To make the torch lighter to carry

• To store extra energy for the battery

If the metal wiring inside a torch becomes exposed, what could happen?

• The torch will be more efficient

• It might cause an electrical short or shock

• The battery will last longer

• The torch will stop using conductors

Why is it important that the battery and wires inside a torch are surrounded by insulators?

• To make the torch look nicer

• To protect users from electric shocks

• To make the torch less expensive

• To help the torch produce more light
