Electrical engineers who deal with systems and circuit theory need to know the terms and functions of the basic circuit element—resistor, capacitor, and inductor—in terms of currentvoltage associations determined by impedance (obstruction). Complex numbers, calculus, and Laplace transforms (see above) are all mathematical concepts used to understand circuit theory.
The best way to understand the basics are through the following simple equations:
