What is DC Voltage?DC Voltage DefinitionDC Voltage (Direct Current Voltage) is a constant Voltage that produces a direct current, with no change in polarity.Voltage SymbolThe DC Voltage symbol is a straight line, often represented by a battery in circuit diagrams.VI characteristics of ideal DC Voltage source and actual DC Voltage sourceDC vs. AC VoltageDC Voltage is constant and zero frequency, while AC Voltage alternates polarity and has a frequency, typically 50Hz or 60Hz.Reducing DC VoltageDi

What is DC Voltage?DC voltage stands for “Direct Current Voltage”. While this sounds confusing, the term “DC” has become used more broadly to refer to a system that has constant polarity. Hence DC voltage is a voltage that produces or would produce a DC current. Conversely, an AC voltage is a voltage that produces or would produce AC current.DC in this context refers more broadly to quantities that don’t regularly change polarity or that have zero (or effectively zero) frequency. AC refers to qu
