Hello, I'm stuck on these questions
Q1) What length of copper wire of diameter 0.38mm would be need to limit the current in it to 0.5A when connected to a 2V battery?
Is that correct?
Q2)A 0.28mm diameter copper wire, 15.0m long, is connected to a 3.0V battery. Find its resistance and the current flowing.
...What do I do next to answer the question?
Thanks a lot.
