Parallel Circuits

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where two or more paths are available for current to flow. If one path is interrupted, current can still flow through the other paths.

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

Back

In a parallel circuit, if one bulb burns out, the other bulbs will still light up because each bulb has its own separate path for current.

What is the role of a switch in a circuit?

Back

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

How do you make a bell ring in a parallel circuit?

Back

To make a bell ring in a parallel circuit, you need to close the switch that connects the bell to the circuit.

Front

What will happen if only one switch is closed in a parallel circuit?

Back

If only one switch is closed, only the components connected to that switch will operate.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, all components are connected in a single path, so if one fails, the entire circuit stops working. In a parallel circuit, components are connected across multiple paths, so if one fails, others can still work.

Front

What is the effect of closing multiple switches in a parallel circuit?

Back

Closing multiple switches in a parallel circuit allows more paths for current to flow, which can increase the brightness of the bulbs.

Front

What happens to the total resistance in a parallel circuit when more branches are added?

Back

The total resistance in a parallel circuit decreases as more branches are added, allowing more current to flow.

Front

What is the function of a light bulb in a circuit?

Back

A light bulb converts electrical energy into light energy when current flows through it.

Front

How can you produce only light energy in a circuit?

Back

To produce only light energy, you need to close the switches that connect the light bulbs without connecting any other devices that produce sound or heat.
