difference between AC and DC power
In this article we are going to discuss about the difference between AC and DC power. Both of electrical power,AC means alternating current and DC means direct current. there are some difference between them.
These are some difference some difference between AC and DC power.
If you fined some in correct above please comment below.
difference between ac and dc power
|
AC(Alternating current)
|
DC (Direct current)
|
|
1. In case AC power , the electron flow constantly in both direction or switching direction sometimes going backward, and sometime going “forward”.
|
In DC power , the electron flow constantly in single direction , or forward direction
|
|
2. Alternating current is more best for transmit electricity over large distance
|
Direct current is less use to transmit electricity over large distance
|
|
3. In case of extra high voltage transmission AC is more efficient than DC.
|
DC power is less efficient to transmits extra high voltage
|
|
4. The frequency of Alternating current is 50 to 60HZ. In India 50HZ frequency used.
|
The frequency of direct current is 0HZ.it DC has not frequency.
|
|
5. Alternating current can be flow both forward and backward direction.
|
Direct current can flow only one direction or forward direction.
|
|
6. Alternating current power factor always lies between 0 to 1.
|
Direct current power factor always being unity
|
|
7. In AC power ,voltage and current does not lies in same phase which mean voltage and current lies in different phase,
|
In case of DC power, voltage and current lies in same phase which cause its power factor is always being unity,
|
|
8. In AC different parameter lies as resistance, capacitance, inductance, Impedance.
|
In DC only one parameter lies which is Resistance.
|
|
9. It can reverse its current direction according requirement
|
9. It cannot reverse its direction
|
|
10. Its (current) magnitude varies with respect to time. dI/dT
|
Its magnitude is always constant
|
|
11. It is efficient for linger distance to provide more power
|
It is not efficient for longer distance
|
|
12. AC curve is sinusoidal
|
DC curve is state line
|
|
13. It required less dangerous
|
It required more dangerous
|
|
14. AC power can be easily step up and step down in power transmission by use of transformer
|
DC power cannot be easily step up and step down it required to convert dc into ac power.
|
|
15. In AC power transmission being corona losses and voltage drop and other type power loss.
|
In case of DC power these type losses is negligible
|
|
16. AC power can be covert into DC power by using of bridge rectifier
|
DC power can be convert into AC power by using of invert er.
