Chapter 6 - Electricity Flashcards
1
Q
What is the equation for change in charge?
A
Change in charge = Current x Change in time
2
Q
What is the definition of Current?
A
The rate of flow of charge
3
Q
What is a coulomb?
A
A coulomb is the amount of charge that passes in one second when the current is one ampere
4
Q
How can we measure Current?
A
We can measure current using an Ammeter connected in series.
5
Q
What is potential difference/voltage?
A
The work done in moving a unit charge between two points
6
Q
What is the equation for potential difference?
A
Potential difference = Work done / Charge
7
Q
How can we measure potential difference (Voltage)?
A
We measure P•D using a voltmeter connected in parallel
