P3.2.2 - Series And Parallel Circuits Flashcards
1
Q
What is a series circuit?
A
A circuit with only on loop and the current is the same everywhere
2
Q
How do you measure the current in a circuit?
A
Use an ammeter
3
Q
How do measure potential difference in series circuits?
A
Connect a voltmeter to both sides of the component
4
Q
What does a voltmeter measure in a battery and in a component?
A
Battery - Rise in potential
Component - Drop in potential
5
Q
Why is does a voltmeter read zero when connected to wires?
A
There is very little drop across the wires
6
Q
What is a parallel circuit?
A
A circuit with more than one loop
Each loop can be worked independently
7
Q
What happens if you measure current at different points in a parallel circuit?
A
The current in the loops add up to the current near the battery
