There are two types of electricity: alternating current (AC) and direct current (DC). AC is the electricity that powers your home and most electronic devices. DC is the type of electricity that powers batteries and some electronic devices.
What Is Ac Electricity?
AC electricity is an alternating current. This means that the direction of the current reverses itself repeatedly. The standard frequency of AC electricity in most countries is 50 Hz, which means that the current alternates at a rate of 50 times per second.
What Is Dc Electricity?
DC electricity is a direct current, meaning it flows in one direction only. It is generated by batteries and solar cells and is the kind of electricity used in your car. The standard voltage of DC electricity is 12 volts.
Difference Between Ac And Dc Power
Some differences between AC and DC power are below:
- Distance: AC can travel long distances without losing power, while DC has a limited range.
- Cost: DC is more expensive to produce than AC.
- Efficiency: AC is more efficient than DC.
- Applications: AC is used for most applications, while DC is used for specific applications such as batteries, solar cells, and electronics.
- Magnets: DC produces magnetic fields, while AC does not.AC electricity flow periodically in a reversed direction, while DC electricity flows in only one direction.
- The current flow: AC changes direction periodically, while DC flows in only one direction.
- Storage: DC can be stored in batteries and capacitors, while AC cannot be stored.
- Usage: AC is used for most applications, while DC is used for specific applications such as batteries, solar cells, and electronics.
- Supply: DC is more expensive to produce than AC.
Application Of Ac And Dc
AC application:
- It is used in domestic appliances such as TV, fan, etc.
- Used in industries for operating high-power motors and lighting purposes.
- Used in subways and railways for running trains.
- Used in street cars and trams.
- Used in aircraft.
DC application:
- Used in automobiles and other battery-operated vehicles.
- Used in computers and electronic devices.
- Used in torches and emergency lights.
- Used in some medical equipment.
- Used as a power supply for welding purposes.
FAQs
Why is AC used over DC?
The main reason that AC is used rather than DC is that it can be easily converted to high voltages using transformers. This means that it can be transported over long distances with minimal losses. DC electricity can also be converted to high voltages, but the process is much less efficient.
What is watt-less current?
Wattles current is the current that flows through an AC circuit when the voltage is not changing. This happens because the capacitance and inductance of the circuit oppose any change in current. When the voltage is constant, the current will flow smoothly without fluctuations.
Why Do We Use AC Instead of DC?
The main reason that AC is used rather than DC is that it can be easily converted to high voltages using transformers. This means that it can be transported over long distances with minimal losses. DC electricity can also be converted to high voltages, but the process is much less efficient.
Conclusion
AC is the type of electricity that powers your home. DC is the type of electricity that powers your car battery. AC is an alternating current, while DC is a direct current. Both have pros and cons, but it comes down to personal preference as to which one you use. DC is slowly becoming more popular as technology advances, but AC is still the standard for most people.
