Transcript of Electrical Safety in the Home

Electricity Safety in the Home What is electricity? Electricity is a physical phenomenon associated with stationary or moving electrons and protons. In other words... Electricity is caused by the flow of positive and negative charges from protons and electrons. Electricity has the ability to do dangerous things
if we don't take the right safety precautions... if we don't pay attention with electricty, lots of things can go wrong.
Fires, being electricuted, and possibly even dying! There There are many safety features in our homes today that help prevent these dangerous occurrences. safety features that include circuit breakers, three pin plugs, fuses and insulators. Circuit Breakers a circuit breaker A circuit breaker is an automatically-powered switch designed to protect and electrical circuit from damage (usually caused by a short circuit or an overload of electricity passing through).

The main purpose of a circuit breaker is to discontinue the flow of electricity in a circuit when a problem is detected. This usually prevents any dangerous situations or any further damage to the circuit itself. Three Pin Plugs A three pin plug is a device which helps connect electrical appliances to a power source safely. three pin plugs are insulated with rubber or plastic. These cover the electrical wires located in the chord itself, they protect us from being electricuted, or from starting any accidental house fires. Fuses A fuse is the weakest point in an electrical circuit. It is a piece of wire that melts when it gets too hot. It will not allow anymore than a certain amount of amps to pass through, if so, the circuit breaks and the flow of electricity is discontinued. Fuses come into place when a short circuit occurs. Short circuits are when the flow of electricity takes a short cut through the circuit. The fuse helps this situation by melting itself and cutting the circuit and stopping any more electricity from passing through the wires. Insulators Insulators are a type of material that will not allow a flow of electricity to pass through them. These materials include: rubber, plastic, glass and wood.

Insulators are a safety feature in our homes as they prevent the occurance of electricution and house fires. They coat metal wires, stopping us from touching them.

Insulators have a high resistance and low volatge passing through them. All of these features contribute in the safety of using electricity.
They prevent dangerous incidents from happening and protect us from any danger. Bibliography Science work
