Why is it important not to touch an electrical wire with your hands?

Never hold an electric appliance in one hand while touching metal objects such as taps, fridges or stoves with the other. This is because our bodies are made up of 70\% of water and they thus become very good electricity conductors. Never use water to put out an electrical fire if the mains are not switched off.

Why is it dangerous to touch a wire?

If you touch it, you may complete a circuit between the live wire and the earth (because you’ll be standing on the floor), so you get a shock. The flow of charge (current) in a circuit can travel in one direction around the circuit only.

Why are we advised not to touch electrical appliances and switches with wet hands?

It is dangerous to handle electrical appliances with wet hands or standing on a wet floor because water is a very good conductor of electricity and when it gets in contact with an electrical appliance, we feel current. Water conducts electricity when it becomes H+ and OH- ion.

Why is it not safe for a person to touch the metal case?

You would get an electric shock if the live wire inside an appliance, such as a cooker, came loose and touched the metal casing. This breaks the fuse and disconnects the appliance.

What will happen if you touch electricity with wet hands?

What are the 3 dangers of electricity?

The main hazards of working with electricity are:

• electric shock and burns from contact with live parts.
• injury from exposure to arcing, fire from faulty electrical equipment or installations.

Is it safe to touch a live wire?

You will receive a shock if you touch a live wire and are grounded at the same time. When a circuit, electrical component, or equipment is energized, a potential shock hazard is present. Black and red wires are usuallyenergized, and white wires are usually neutral.

What happens if you touch a switch with your wet hand?

(c) Switches should not be operated with wet hand : Water is a good conductor of electricity as it contains salt and impurities. When we touch the switch with wet hand, it is possible that electric current will pass through our body and we get

Why we should not use many electrical devices simultaneously?

Hence, we must not use many electrical simultaneously. (c) Switches should not be operated with wet hand : Water is a good conductor of electricity as it contains salt and impurities. When we touch the switch with wet hand, it is possible that electric current will pass through our body and we get
