Electrical Circuits

Electrical circuits are found everywhere in our society. The original discovery of electron movement has morphed into electrical transmission and distribution in applications from residential to heavy industrial power.

Listed below are the various topics covered in this section which will give you a 360° view of circuit theory and application.

• What is a Circuit?
• Learn how electron flow creates circuits and how circuits work.


• Series and Parallel Circuits
• This section discusses the difference between series and parallel circuits and how each works.


• Resistance and Conductance
• How easy or hard is it for electrons to flow through a circuit? Find out here.


• Ohm's Law and Circuits
• Georg Simon Ohm's theories were published in full in 1827, but they still hold true today by explaining circuit theory.


• Ohm's Law Diagram
• This handy diagram shows the relationship between volts, amps, watts and ohms.


• Circuit Breakers
• circuit Breakers can literally make or break a circuit. Read about them here.
