What are Voltage Regulators?Voltage Regulator DefinitionA voltage regulator is defined as a device that keeps the voltage level within suitable limits to protect connected equipment.Voltage regulator classification Linear Voltage Regulators Switching Voltage RegulatorsVoltage regulator application Power distribution system Automobile alternator Power station generator plant Computer power supplies

What is DC Current?Direct Current DefinitionDirect current is a constant and unidirectional flow of electric charge, moving from a negative to a positive terminal.AC vs DCDirect current flows in one direction and is used in applications requiring stable voltage, while alternating current can reverse direction and is typically used where varying power levels are needed.DC Current SymbolThe symbol for DC current is a straight line, indicative of its consistent and unchanging direction.Measurement
