Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
A charge of passes through a wire in .
- What is the current?
- How much charge passes in at this current?
Need a reminder? The key ideaShow
Current is the charge passing each second: , in amperes (). One electron carries . The conventional current goes from to outside a cell; electrons drift the other way.
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.
