Different between Alternating current and Direct current.

 In dynamic electricity there are two types of current which are ac and dc where ac stands for alternating current and dc stands for direct current.

What is ac?

Alternating current is the current in which it moves in a cycle where half cycle is positive and next half cycle is negative as in the given figure.



Alternating current is commonly used in house appliances and industrial machinery because of its benefits.

What is dc?

Different from alternating current, direct current moves in a single direction in a straight path. There is no any positive or negative cycle because of single direction current. It is least used in home appliances and industrial propose.

Difference between ac and dc

 

                      AC

                       DC

-It stands for alternating   current.


-It has frequencies.


-We need transformer to change ac voltage.


-Generator and Alternator are used to produce ac electricity.


-Ac can be transmitted into long distance in specific voltage.


-In ac power factor is between or equal to 0 to 1.


-Transmission loss is very low in ac.


-It stands for direct current.

 

-It does not have frequency.

 

-We need chopper to change dc voltage.


-Only generator is used to produce dc electricity.


-Dc can’t be transmitted into long distance in specific voltage.


-But in dc power factor is always 1.


-But in dc transmission loss is very high.

How hydroelectricity is generated?

Image
  Before knowing about how hydroelectricity is produced we have to know about what do you mean by hydroelectricity. Hydroelectricity is the electrical energy which is produced by converting the mechanical energy of the water to electrical energy. There are total three sections in hydroelectricity power plant. 1)   Dam:     It is also known as the reservoir of water. In dam we collect water for the future propose cause in some season due to lack of water we have to close the production but as dam has the reservoir of the water we can use it in that season when we lack water and produce electricity.     Also there are some hydro power which doesn’t has dam and use running water for producing electricity which is also known as RUN OF THE RIVER hydro power plant.      2. Tunnel :  Tunnel is the part of the power plant which is responsible for making water flow from dam towards the turbine. There are also various types of tunnel used as types...

Why Birds Don't get Shock while Sitting on Electric live wire?

Image
We had seen many times that birds are sitting on overhead wires but also it doesn’t get electric shock, here are some reason which leads to make safe from electric shock for birds: 1.  Birds are not touching the ground or anything in contact with ground or neutral line, so the electricity will stay in the power line. 2.  As we know that bird place both leg on same wire of same voltage so because of no potential difference in two legs of bird there no electricity is conducted. 3.  Electricity always choose a low resistance path so in bird and wire case wire has low resistance and bird leg has high resistance so here electricity will easily flow through wire rather than bird leg  so as no current flow through bird it will no get electric shock.
