Voltage sources are important electrical elements.

• Why learn about voltage sources?
• Many electrical elements are voltage sources of one sort or another.  Things like batteries, wall plugs, stereo amplifiers, antennas receiving signals and many other devices are all voltage sources of some sort.  The concept of a voltage source is basic to understanding the operation of almost any electrical device.
• What should you know to learn about voltage sources?
• If you want to learn about voltage sources, you first need to understand what voltage is.  If you want a Study Guide for voltage, click here.
• What do you need to know about voltage sources?
• Many of the concepts of voltage sources are build around the concept of an ideal voltage source.
• Real sources - unlike ideal voltage sources - are often modelled using a Thevenin Equivalent Circuit.
• How do you use voltage sources?
• Voltage sources are the devices that power any sort of electrical and/or electronic device.  You will encounter them almost every time you encounter an electrical or electronic device.
• What if?
• There are times when
