Definition of solar cell Solar cell is that cell which converts light energy to electrical energy. Working principal of solar cell is related to emission of light or absorption. It is an electronic device. Actually solar cell is p-n junction device which convert solar energy to electrical energy. … [Read more...] about How a solar cell works
The substances by which electricity or charges flow is called medium. It is classified into three types are (i) Conductor, (ii) Semiconductor (iii) Non conductor … [Read more...] about Electrical conductivity very basic concept
Types of electricity is based on conductivity and nature of electricity according to nature there are two types of electricity viz Current electricity Static electricity Current electricity: Electricity means charge. When the charge does not remain confined in one place, it moves one place to another place is called current electricity. We use current electricity in … [Read more...] about Different Types of Electricity – Definition Basic Concept
There are four thermodynamic process basically isothermal, adiabatic, isochoric process, isochoric processes. The branch of physics where relation between heat and work done is discussed called thermodynamics. In thermodynamic process firstly we have to know about thermodynamic system. What is thermodynamic system? The system is a closed area where thermodynamic substance … [Read more...] about Thermodynamic process
Amplifier is an electronic device. The device which increases the value of a signal is called amplifier. In input a weak signal is applied, in output a strong, same shape signal is gained. Amplify means to increase the value of something. Transistor is used in amplifier. It can amplify a signal many times. In two ways a transistor can amplify a signal (i) by using high value … [Read more...] about What is Amplifier?
