Types of circuits

Components in an electric circuit can be set up in:

• series

• parallel

• a combination of both (mixed circuit)

• All the answers are true

A SERIES CIRCUIT HAS MORE THAN ONE PATH TO FOLLOW

• TRUE

• FALSE

In a series circuit, if one bulb goes out, the rest stay on

• TRUE

• FALSE

Answer explanation

•They all go out.

•If the circuit is broken at any point there won’t be any current that will flow.

•The other bulb would not be able to light up because the flow of electric current would have been interrupted.

The amount of current is the same through any component in a series circuit

• TRUE

• FALSE

Answer explanation

•This is because there is only one path for current flow in a series circuit.

•The rate of flow at any point in the circuit must be equal.

What is the current at each component?

• 0,3 A

• 0,1 A

• 0,9 A

• 300 mA

Resistance is a measure of the opposition to current flow in an electrical circuit.

• TRUE

• FALSE

The total resistance in a series circuit is not the sum of the resistance at each component:

• TRUE

• FALSE

Answer explanation

The total resistance of any series circuit is equal to the sum of the individual resistances.

Resistance is measure in Amperes?

• TRUE

• FALSE

Answer explanation

Resistance is measured in ohms.

Current is measured in amps
