A source that does not depend on any other quantity (like voltage or current) in the circuit is termed an independent source. The following figure shows some common symbols for representing independent voltage sources: Figure 6. (a) DC voltage source; (b) battery symbol; (c) AC voltage sou...
DC voltage source This is called direct current because it has just one direction. The current has one direction as the source maintains the same polarity of output voltage. The opposition to load current inside the DC source is known as internal resistanceRi. ...
The circuit includes an energy source (a battery, for instance) that produces voltage. Without voltage, electrons move randomly and fairly evenly within a wire, and current cannot flow. Voltage creates pressure that drives electrons in a single direction. The circuit forms a closed, conducting loo...
Electric Current Isn’t “Used up” The battery’s voltage is what pushes the charges around the circuit. And here’s an extremely important fact: A circuit is always completely filled with electric charges. Even when there’s no battery connected. ...
A constant current source is a power source which provides a constant current to a load, even despite changes and variance in load resistance. In other words, the current which a constant current source provides is steady, even if the resistance of the load varies. ...
Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.
