Op Amp Differential Amplifier Circuit Diagram and its Operation: An ideal difference amplifier amplifies only the difference between two signals; it rejects any common signals to the two input terminals. For instance, a microphone system…
Op Amp Comparator Circuit: Op Amp Comparator Circuit - In the opamp applications discussed so far, the amplifiers use negative feedback. Under normal conditions, when negative feedback is used in such a circuit, the amplifier…
Op Amp Circuit Bandwidth and Slew Rate Test: Low Cutoff Frequency - Op Amp Circuit Bandwidth and Slew Rate Test are direct-coupled internally, so where they are employed in direct-coupled applications, the circuit lower cutoff…
Op Amp Assumptions: We can make two Op Amp Assumptions which are realistic and simplify the analysis of op-amp circuits to a great extent. The Op Amp Assumptions are useful and can be used to…
One Line Diagram of the 4 Bus System: A power system comprises several buses which are interconnected by means of transmission lines. Power is injected into a bus from generators, while the loads are tapped…
On Off Controller or Two Position Controller: The On Off Controller or two position controller is the simplest, cheapest and the most used controllers. It is used in domestic heating systems, refrigeration, water tanks, etc.…
Oil Pressure Governor and its Working Principle: The primary purpose of a governor for a hydro electric unit is to control the speed and loading of the unit. It is accomplished by controlling the flow…
Oil Circuit Breaker Diagram: In such Oil Circuit Breaker Diagram, some insulating oil (e.g., transformer oil) is used as an arc quenching medium. The contacts are opened under oil and an arc is struck between…
Oil Circuit Breaker: Oil Circuit Breaker are extensively employed in our power systems. In these the properties of the arc are employed for arc extinction. Thus by using arc energy to crack the oil molecules,…
Octal Number System (Definition, Conversions & Examples): The number system with base (or radix) eight is known as the octal number system. Although we can use any eight digits, it is customary to use the…
