Difference Between Ac And Dc

 7 Differences Between Ac And Dc

S.NO.	Ac	Dc
1.	AC (alternating current) is an electric current that periodically changes direction.	DC (direct current) is an electric current that flows in only one direction.
2.	AC is produced by generators and is commonly used in power transmission and distribution systems.	DC is produced by batteries and is commonly used in electronic circuits.
3.	AC voltage and current oscillate at a certain frequency, typically 50 or 60 Hz.	DC voltage and current are constant.
4.	AC voltage and current can be easily transformed using transformers.	DC voltage and current cannot be transformed in the same way.
5.	AC power can be transmitted over long distances with minimal loss.	DC power is typically limited to shorter distances due to the loss of energy through the resistance of the conductor.
6.	AC systems require more complex protective devices, such as circuit breakers and fuses, due to the potential for electrical arcs and high fault currents.	DC systems are generally simpler and require fewer protective devices.
7.	AC motors are more common than DC motors due to their ability to operate at a range of speeds and the ease with which their speed can be controlled.	DC motors are less common than AC.
