Basic Theory
Publisher Summary
This chapter helps learn the basic theory of electricity. It begins with the description of Ohm’s law, which states that voltage equals current multiplied by resistance. This law is one of the best taught principles in school for the budding engineer or technician. All other rules are based on this foundation. Its fundamental fact is that resistance impedes current flow. This impedance creates a voltage drop across the resistor that is proportional to the amount of current flowing through it. The chapter considers two other types of impedance that can be found in a circuit: inductive reactance and capacitive reactance. Every wire, trace, component, or material in the circuit has these three components in ...
