The symbol for resistance is R, it is measured in ohms \((\Omega )\). The symbol for current is I, it is measured in amperes \((A)\).

A poor conductor, or insulator, has high resistance. The two main ways of increasing the current in an electrical circuit are by increasing the voltage or by decreasing the resistance. If you ...

The book includes extensive problem sets that facilitate computer-based learning of electromagnetics and the application of QuickField and MATLAB illustrating some of the basic concepts in ...

What size circuit will you need for the space heater ... When you look at the Ohm’s Law Wheel, select this formula: I = W/E (amps = watts ÷ volts); I = 5,000 watts ÷ by 240 volts; I = 20.8 ...

Let’s look at an example of these relationships, starting with voltage, resistance and current (Ohm's Law). This diagram ...
