Circuits And Potential Difference Flashcards
1
Q
What do you need to make current flow in a circuit?
A
Potential difference
2
Q
How are 2 sides of batteries differently charged?
A
There are substances that react to separate the charges, making one side of the battery positively charged and the other side negatively charged
3
Q
What is potential difference measured in?
A
Volts
4
Q
How do you measure potential difference?
A
Voltmeter
5
Q
How is energy transferred calculated in a circuit?
A
Energy transferred (J) = potential difference (V) x charge (C)
