What is DC Voltage?

DC Voltage Definition

DC Voltage (Direct Current Voltage) is a constant Voltage that produces a direct current, with no change in polarity.

Voltage Symbol

The 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 source

DC vs. AC Voltage

DC Voltage is constant and zero frequency, while AC Voltage alternates polarity and has a frequency, typically 50Hz or 60Hz.

Reducing DC Voltage

Diodes and resistors can reduce DC Voltage, with diodes creating a Voltage drop and Resistors forming a Voltage divider circuit.

How to Step-up DC Voltage

Step up the DC Voltage with a boost converter
