Starting with its similarity
with a hydraulic supply circuit, we intend to sketch the most important
characteristics and laws related to an electric circuit. We will assume from the
start, that the student understands the concepts of charge, field and
electric potential covered in the unit on electricity. If this is so,
then you can proceed. If not, we suggest you first study the chapter on
Electricity. Click on next to see the
objectives we propose in detail. |
