Voltage is the rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in Volts. Voltage is often described as the difference in charge between two points.
Two types of Voltage Sources
- DC Source
- AC Source
Greater the voltage, greater the flow of conducting or semi-conducting medium for a given resistance to flow. Voltage is symbolized by uppercase italic letter V or E
The standard unit is the volt, symbolized by non-italic uppercase letter V
