Flashcards in P2.1.4 - Series and Parallel Circuits Deck (20)
1
Q

Identify the potential difference across each component in the parallel circuit. What is the rule?

A

Both are 6V

The potential difference across each component in a parallel circuit is the same as the potential difference (rating) of the battery.

2
Q

A parallel circuit contains ______ or more loops

A

2

3
Q

Identify the potential difference across each component in the series circuit. What is the rule?

A

Both are 3 V

The potential difference of every component in a series circuit adds up the the potential difference (rating) of the battery.

4
Q

Identify the type of circuit shown.

A

Series Circuit

5
Q

Identify the type of circuit shown.

A

Series Circuit

6
Q

What makes parallel circuits more useful than series circuits? (the diagram may help)

A
• If one bulb breaks, the other bulbs will stay on.
• All bulbs are the same brightness.
• You can control each bulb by putting a separate switch in each ‘branch’.
7
Q

Identify the type of circuit shown.

A

Series Circuit

8
Q

Identify the type of circuit shown.

A

Parallel Circuits

9
Q

What happens to the current at the branch after A2?

What will the current at A4 read?

A

It recombines with the current travelling from A3.

So the current at A4 will be 1 A, the same as the current coming out of the battery.

10
Q

What happens to the current when it reaches the branch after A1?

What will the current be at A2 and A3?

A

The current is shared between the two branches.

1. 5 A at A2
2. 5 A at A3
11
Q

What happens to the current in a parallel circuit if you add more branches?

A

The current in each branch stays the same.

The total current being pushed by the battery increases.

12
Q

In which direction does current (charge per second) travel around a circuit?

A

From the positive side of a cell or battery, to the negative side (if conventional current).

From negative to positive (if talking about direction electrons travel)

13
Q

Identify the type of circuit shown.

A

Identify the type of circuit shown.

A

Parallel Circuits

17
Q

Name the 2 types of circuit.

A

Series Circuit

Parallel Circuit

18
Q

Identify the type of circuit shown.

A

Parallel Circuit

19
Q

What happens to the current (charge per second) flowing through a circuit as you add more components.

A

The current will get smaller.

20
Q

Describe the current that ammeter’s A1, A2 and A3 will show.

A

The current (charge flow per second) is the same throughout a series circuit.

All ammeters will show the same value.
