Unit 5. Ohm's Law


The main topic in this unit is the most fundamental equation in electronics: Ohm's Law. This is an equation that relates voltage, current, and resistance. We'll start to discuss a topic that's not covered in the book, but that's important for a technician: how to estimate answers to mathematical problems without using a calculator. Finally, we'll look beyond series circuits and parallel circuits to more complicated circuits called series-parallel circuits.
