Electrical Safety

The video tutorial explains the dangers of fires caused by faulty wiring and short circuits. It highlights the role of the ground prong in appliances to prevent electric shocks. The video also covers how fuses and circuit breakers function as safety mechanisms to prevent circuit overloads, with a focus on the differences between older and modern buildings' electrical safety features.

What is the primary function of the ground prong in electrical appliances?

• To provide additional power

• To enhance appliance efficiency

• To stabilize voltage

• To protect against short circuits

What happens inside a fuse when too much current flows through it?

• It contracts

• It melts

• It solidifies

• It expands

Why do fuses need to be replaced after they have melted?

• They are designed for single use

• They change shape permanently

• They become too hot to handle

• They lose their conductivity

What is a key advantage of circuit breakers over fuses?

• They are cheaper

• They are more compact

• They can be reset without replacement

• They conduct more electricity

In modern buildings, what is typically used instead of fuses?

• Voltage regulators

• Ground prongs

• Surge protectors

• Circuit breakers
