Circuits

Question 1

What is a series circuit?

Answer 1

Components that are connected one after another on the same loop of the circuit are connected in series. The current that flows across each component connected in series is the same.

Question 2

What is a parallel circuit?

Answer 2

Components that are connected on separate loops are connected in parallel. The current is shared between each component connected in parallel. The total amount of current flowing into the junction, or split, is equal to the total current flowing out. The current is described as being conserved.

Question 3

How is ammeter linked to the component?

Answer 3

The ammeter must be connected in series with the component.

Question 4

What is potential difference measured in?

Answer 4

Potential difference is measured in volts.

Question 5

How is potential difference measured?

Answer 5

Potential difference across a component in a circuit is measured using a voltmeter.

Question 6

What happens to potential difference when there are more cells in a circuit?

Answer 6

When more cells are connected in series in a circuit, they produce a bigger potential difference across its components.
