2a.7 - Circuits in Series and in Parallel

Question 1

What happens to potential difference when it is connected in a series circuit?

Answer 1

Potential difference is shared

Question 2

What happens to current when it is connected in a series circuit?

Answer 2

It is the same everywhere

Question 3

What happens to resistance when it is connected in a series circuit?

Answer 3

It adds up

Question 4

What happens to cell voltage when it is connected in a series circuit?

Answer 4

It adds up

Question 5

What is connected in series in real life?

Answer 5

Fairy lights

Question 6

What happens to potential difference when it is connected in a parallel circuit?

Answer 6

It is the same across all componants

Question 7

What happens to current when it is connected in a parallel circuit?

Answer 7

Shared between branches (A = A1 + A2 current at the end of the circuit is divided by number of branches to get the current for each branch)

Question 8

Are ammeters always connected in series or in parallel?

Answer 8

Series

Question 9

Are voltmeters always connected in series or in parallel

Answer 9

Parallel

Question 10

Why are parallel circuits essential in a car?

Answer 10

• Everything can be turned off and on separately

- Everything always gets the full voltage from the battery
