Safety in Using Electricity: Circuit Protection

It occurs when a person touches live or damaged wires, causing current to flow through the body.

• Double insulation

• First insulation

• Electric shock

• Short circuits

It occurs when wires accidentally touch, forming a path of a very low resistance.

• Double insulation

• First insulation

• Electric shock

• Short circuits

It protects the user of the appliance from an electrical shock by preventing any possibility of the external casing becoming live.

• Double insulation

• First insulation

• Electric shock

• Short circuits

What are the devices we can use for safe usage of electricity at home?

• Fuse, Circuit Breaker,Earth wires,Three pin plug

• Fuse, Circuit Breaker, Tree wires,Three pin plug

• LAN Wires, Circuit Breaker,Earth wires,Three pin plug

• Fuse, Circuit Breaker, Earth wires, Switches

A _____is a thin conductor with a low melting point that is attached to a circuit. When heats up and melts then current in the circuit reaches a safe limit. As a result, the circuit is broken and the current flow is halted.

• Earth wires

• Circuit Breaker

• LAN Wires

• Fuse

It acts as an automatic fuse that whenever there is an excess amount of current it automatically switches off, thus breaking the circuit. It can then be turned back on like a switch.

• Earth wires,

• Three pin plug

• Circuit Breaker

• Fuse

__________ or grounding protects us from electric shocks by sending excess current into the ground. If short circuiting occurs, the current will flow directly into the earth through this.

• Earth wires

• Three pin plug

• Circuit Breaker

• Fuse

__________can be usually seen in appliances having three pins in their plug. Two pins of the plug connect the appliance to the main supply while the third pin connects it to the earth wire.

• Earth wires

• Three pin plug

• Circuit Breaker

• Fuse

It insulates the electrical cable from the internal component of the appliance.

• First Insulation

• Second Insulation

• Circuit Breaker

• Wires

It is a set of physical phenomena associated with the presence and motion of matter that has a property of electric charge.
