Series and Parallel Circuits

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where the components are connected end-to-end, so that the same current flows through each component.

Front

What happens to the current in a series circuit?

Back

In a series circuit, the same current flows through all components.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where the components are connected across common points or junctions, allowing multiple paths for the current.

Front

What happens if one component fails in a parallel circuit?

Back

If one component fails in a parallel circuit, the other components continue to operate.

Front

What is the unit of electric current?

Back

The unit of electric current is Amps.

Front

What happens when a switch in a circuit is opened?

Back

When a switch in a circuit is opened, current stops flowing, and all components connected to that circuit turn off.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected in a single path, while in a parallel circuit, components are connected across multiple paths.

Front

What is the effect of adding more light bulbs in a series circuit?

Back

Adding more light bulbs in a series circuit increases the total resistance, which decreases the current and makes the bulbs dimmer.

Front

What is the effect of adding more light bulbs in a parallel circuit?

Back

Adding more light bulbs in a parallel circuit does not affect the brightness of the other bulbs, as each bulb has its own path for current.

Front

What is voltage?

Back

Voltage is the electric potential difference between two points in a circuit, measured in Volts.
