Why do we need fuses and circuit breakers?
Fuses and circuit breakers protect electrical circuits from too much current.

What could happen without them?
Without fuses and circuit breakers, wires could overheat, electrical devices could be damaged, and fires could start, making homes unsafeWhy do we need fuses and circuit breakers?

Electricity: Electricity is the flow of electric energy.

Electrical Circuit: An electrical circuit is a closed path that allows electricity to flow.

Two Components: Battery and bulb.

# data[].attributes.body
Conductor: Allows electricity to flow through it (e.g., copper, metal).

Insulator: Does not allow electricity to flow easily (e.g., rubber, plastic).

Voltmeter → Voltage → Volt (V)

Ammeter → Current → Ampere (A)

Ohmmeter → Resistance → Ohm (Ω)

Electricity is the flow of electrical energy. An electrical circuit is a complete path that allows electricity to flow, and two components of a circuit are a battery and a bulb.

A conductor is a material that allows electricity (or heat) to flow through it easily, like copper or aluminum.

An insulator is a material that does not allow electricity (or heat) to flow through it easily, like plastic, rubber, or wood.

We need fuses and circuit breakers to stop too much electric current and keep us safe. Without them, wires could overheat, damage appliances, or even cause fires.

Voltmeter: measures voltage — unit: volts (V)

Ammeter: measures current — unit: amperes (A)

Ohmmeter: measures resistance — unit: ohms (Ω)

If you plug a phone charger, hair dryer, and microwave into one extension cord, it could overload the circuit.

This is dangerous because all three devices use a lot of electrical current. The extension cord may not handle that much power, so it can overheat, melt, or even start a fire. It could also cause the fuse or circuit breaker to trip and cut the electricity.

We need fuses and circuit breakers to protect our homes and electrical devices from too much current (overload) or short circuits. They automatically stop the electricity when it becomes dangerous.

If we didn’t use them, the wires could overheat, melt, or even start a fire, which could damage appliances and be very dangerous for people in the house.
