The work done to move a charge of 8 C between two points is 44 J.
Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
The work done to move a charge of between two points is .
- What is the potential difference between the points?
- How much work moves between the same points?
Need a reminder? The key ideaShow
The potential difference is the work done per coulomb: , in volts (). So . An ammeter goes in series; a voltmeter goes in parallel.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
