  CAPACITANCE OF  CONDENSER :    The charges required to produced a certain difference of potential between the plates of a condenser is a constant ratio to the potential. This constant ratio is called capacity of condenser.  MICA CAPACITORS : Silver mica capacitors are high precision, stable and reliable capacitors. They are available in small values, and are mostly used at high frequencies and in cases where low losses (high Q) and low capacitor change over time is desired CAPACITOR : A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals. CAPACITANCE: Capacitance is the ratio of the amount of electric charge stored on a conductor to a difference in electric potential. There are two closely related notions of capacitance: self capacitance and mutual capacitance. PRINCIPAL OF CAPACITOR: A capacitor works on the principle that the capacitance of a conductor increases appreciably when a...

  What are Reversible Processes ? A thermodynamic process (state i → state f ) is said to be reversible if the process can be turned back such that both the system and the surroundings return to their original states, with no other change anywhere else in the universe. As we know, in reality, no such processes as reversible processes can exist. Thus, the reversible processes can easily be defined as idealizations or models of real processes, on which the limits of the system or device are to be defined. They help us in incurring the maximum efficiency a system can provide in ideal working conditions and thus the target design that can be set.  What are Irreversible Processes? An irreversible process can be defined as a process in which the system and the surroundings do not return to their original condition once the process is initiated. Taking an example of an automobile engine, that has travelled a distance with the aid of fuel equal to an amount ‘x’. During the process, th...

What is Heat Engine? A heat engine is a device that converts heat to work. It takes heat from a reservoir then does some work like moving a piston, lifting weight etc and finally discharges some heat energy into the sink. Schematically it can be represented as
