DC motor DC motor is a motor running on a direct current. which converts electrical energy into mechanical energy. We can run direct the DC motor to any type of battery or to the Solar panel.  Construction of DC motor DC motor consists of yoke, armature, brush, commutator, magnetic pole and pole shoe . Next we will know in details about all these parts.  yoke Yoke is called the outer part of the DC motor, it is made of cast iron and cast steel. It is in the shape of a hollow cylinder, and inside it is an armature and a pole.  armature It is the rotating part of a motor, which rotates inside the motor. The armature is made from laminated strips of silicon steel. There is a shaft in the armature, with the help of which we can convert electric energy into mechanical energy. Commutator Commutator is a main part of DC motor, on top of it brush of DC motor is attached. The inductor itself converts the bidirectional signal into unidirectional signal. The commutator is connected to

Tesla car battery/Technology/Life and Price

Tesla car is the best and new generation electric car in the world. Till now Tesla's car is being sold in 180 countries. Tesla is a USA company, which exclusively manufactures electric vehicles. Tesla's car is made of such advanced technology that you will not see any shortcoming in it.  Big size batteries are used in all the electric vehicles you have seen till now. Which is much bigger in size. And its life is also very short. Compared to a Tesla car battery.  Lithium ion cell has been used in Tesla electric car. A cell is of 4.2 V. A total of 2976 cells have been used in a car. 5.3 kW power is made by connecting all in parallel and series. 31 battery packs are made from the cells. Each battery pack contains 96 Lithium Ion cells.  The lithium ion cells for Tesla's electric vehicle are manufactured by the Japanese company Panasonic.  What Battery was used in Tesla's car?  Generally, a large size battery is seen in any electric vehicle, which is also very heavy. But Tes

What is electric current?/ AC and DC current

ELECTRIC CURRENT  Electric current is made up of a group of electrons. Whenever electrons flow in a conductor, that flowing electron is called current or electricity.  types of electric current Current is of two types, AC or DC current   The full name of AC Current is Alternative Current.  The full name of DC current current is Direct Current. difference between ac and dc AC Current   - AC Current is called alternating current. Alternating current is an electric current that continuously changes direction as it flows. AC current flows with Hz. Usually AC current flows at 50 or 60 (hz) hertz. We cannot store AC current in any battery as AC current. (To store it, we have to convert it to DC first)   Image source by Google-https://dam-assets.fluke.com/s3fs-public/6004181-dmm-whatis-frequency-715x360-2.jpg We can increase or decrease the voltage of AC current with the help of transformer. When AC current flows, it flows in a positive or negative cycle. Current flows in both the
