 What Is Diode?

A diode is an electronic component that allows current to flow in only one direction. It is made up of a p-type semiconductor and an n-type semiconductor that are fused together. The p-type semiconductor has an excess of positively charged holes, while the n-type semiconductor has an excess of negatively charged electrons.


When a voltage is applied to the diode in the forward direction (positive to the p-type and negative to the n-type), current flows easily through the diode. This is because the positive voltage attracts the electrons in the n-type semiconductor, and the negative voltage attracts the holes in the p-type semiconductor. The result is a current flow from the positive side of the diode to the negative side.


In the reverse direction (positive to the n-type and negative to the p-type), the diode acts as an insulator, and virtually no current flows. This is because the negative voltage repels the electrons in the n-type semiconductor, and the positive voltage repels the holes in the p-type semiconductor. The result is a high resistance to current flow from the positive side of the diode to the negative side.


How To Diodes Works

A diode works by allowing current to flow in only one direction. It is made up of a p-type semiconductor and an n-type semiconductor that are fused together to form a p-n junction. The p-type semiconductor has an excess of positively charged holes, while the n-type semiconductor has an excess of negatively charged electrons.


When a voltage is applied to the diode in the forward direction (positive to the p-type and negative to the n-type), current flows easily through the diode. This is because the positive voltage attracts the electrons in the n-type semiconductor, and the negative voltage attracts the holes in the p-type semiconductor. The result is a current flow from the positive side of the diode to the negative side.


In the reverse direction (positive to the n-type and negative to the p-type), the diode acts as an insulator, and virtually no current flows. This is because the negative voltage repels the electrons in the n-type semiconductor, and the positive voltage repels the holes in the p-type semiconductor. The result is a high resistance to current flow from the positive side of the diode to the negative side.

Diodes are used in many electronic applications, such as rectifiers, voltage regulators, and signal modulators. They are also used in power supplies, where they convert AC voltage to DC voltage by allowing current to flow in only one direction. Diodes can also be used for switching applications, where they can be used to turn a circuit on or off. Overall, diodes are an essential component in modern electronics and play a critical role in many applications.

ERTHING

ERTHING                        Electricity is beneficial for us, but its loss is even more. Electricity can take our lives even if it does not go well. Now we can not get away from electricity because electricity has become part of our life. Light in the darkness, fan in the heat, so much of the electricity around us that we They even use it inadvertently. Along with this, the risk goes up. For this reason, we must definitely adopt a path of goodwill which can secure us and our own electricity so we must definitely do our work in our home to avoid all these. But first, do you know what the meaning is?  What is Erthing?            We have so many electric appliances in our house around us that sometimes we have been using it. Therefore the electrical equipment is in contact with our body, and therefore whenever there is a fault in the instrument then the body of the instrument comes in contact with us, so that the current passes through our body and we feel shock O

Distribution Transformer and Power Transformer

Distribution Transformer:                                     The transformer is used in the distribution of electrical energy. It is called Distribution Transformer. Its rating is 200 KVA and it is a step down type. In this transformer whether the load is loaded or not, it is functioning 24 hours a day. This means that iron lasts continuously throughout the day while copper is based on the load load. So much so that the load more loads of copper loses and loads less as copper Iron deficiency in such transformer should be lower than Copper Loss. In other words, the transformer's efficiency should be greater on the 50% load. Such transformer's voltage regulation should be good. Power Transformer:                                      The transformer that is used for the transmission of electrical energy is called a power transformer. The rating of this transformer is 200KVA. Power transformer can be used to step up or step down the voltage on both ends of the power l

D.C 3 POINT STARTER

                                 It can also be called a three point starter. Its structure is shown in Figure. To start the motor, the handle is moved from off position to the first contact position. The total obstacle is in the armature circuit, the field connection is connected directly to the supply through a volt coil. Comes in as soon as the speed of the motor increases in the same way as the archete back emf emits and decreases in the value of current Now the handle is moved to the second step. Again this type of function will be done eventually at the last step of the handle. This time the armature will connect directly to the supply and this time the handle does not come with a no-volt coil. The magnet will hold the handle in the walt coil, and the motor will not need to hold the handle to continue and the motor will rotate in full speed.                   Mechanism of 3 points Starter is done so that if the magnetism of the nvc coil is exhausted for any reason, and the
