Electric Circuits

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electricity to flow from a power source, through components like wires and bulbs, and back to the power source.

What is the purpose of insulation on electrical wires?

Back

Insulation, usually made of plastic, is used to cover electrical wires to prevent accidental contact with the wire, ensuring safety by reducing the risk of electric shock.

Front

What is a switch in an electric circuit?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of electricity.

Front

What happens when a switch is closed?

Back

When a switch is closed, it completes the circuit, allowing electricity to flow and power the connected devices, like lamps.

Front

What is a battery?

Back

A battery is a device that stores chemical energy and converts it into electrical energy to power circuits.

Front

What is a complete circuit?

Back

A complete circuit is a closed path that allows electricity to flow uninterrupted from the power source to the load (like a bulb) and back.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected one after another, so the same current flows through all components.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where components are connected across the same voltage source, allowing multiple paths for current to flow.

Front

What happens if one bulb in a series circuit burns out?

Back

If one bulb in a series circuit burns out, the circuit is broken, and all bulbs will go out.

Front

What happens if one bulb in a parallel circuit burns out?

Back

If one bulb in a parallel circuit burns out, the other bulbs will remain lit because they have separate paths for current.
