 Smart grid technology is a very important technology for which current loss is very low.  It balances the supply and demand of current. Smart grid concept || how to work smart grid technology  If more current is induced in a given plant than its demand, then it is necessary to send the excess current through the grid to another place where there is a supplied low. Advantages of grid The resulting loss is very low. And those found companies will be able to sell their extra power

 Solar energy are three types 1. Photovoltaic solar energy 2. solar thermal energy 3.consentrating solar energy Photovoltaic solar energy The energy generated by incident solar energy into electricity is termed as photovoltaic solar energy This is done using photovoltaic solar cell Photovoltaic solar cell is two types  1 monocrystalline 2 polycrystal line Solar thermal energy Solar thermal energy is the heat energy derived from the incident solar energy. this is used by solar heating panel. Consentrating solar energy Concentrating solar energy works like a thermal power plant.  When many mirrors are placed together in sunlight, the light from all the mirrors is placed in one place by consenting in one place.  There the water in the boiler is heated to the temperature of sunlight and then electricity is generated like a thermal power plant. Consentrating solar power

  What is the solar energy? Solar energy is the energy which is coming from Sun This energy is the from of solar radiation that is producing a solar electricity. Solar panels Why do we need solar energy? Because, solar power is free available from Sun and it does not produce pollution or green house gases.  Its easy to install  Type of solar energy Photovoltaic solar power Solar thermal energy Concentrated solar power

what is drift current ?   When a voltage is applied to a semiconductor or conductor The free electrons try to move in a stregth line towards the positive terminal of the battery The election moving towards positive terminal collide with the atom of semiconductor and along its way Each time the electron strike an atom and it resound in a random direction But still the Applied voltage make the electron drift towards the positive terminal  Due to this drifting process a current comes and it is called drift current

 electrical resistance is the property of a material which it oppose the flow of electron through  the material .thus resistance restricts the flow of electric current through the material .the resistance usually denoted by the symbol 'R' and units is ohm                                                                                                                                                                                                                  ...

The polarity of a transformer identify the relative direction of voltage in the two winding  . we know the relative polarity for operating transformer is parallel
