The Non-Conventional Energy Sources are those which are available for us at any time and are free of cost.
-
The Conventional Energy Sources are helpful in producing electrical power generation from Hydro, Thermal, Nuclear and Diesel power stations.
-
The precision rectifier has the capability of rectifying voltages which are of smaller magnitude than the forward voltage drop.
-
The circuit which produces the samples of the input voltage and holds those values for a definite amount of time is sample and hold circuit.
-
An interrupt is a condition that arises during the working of a microprocessor. The interrupts of 8086 initiate interrupt service through ISR
