Heat Capacity of Calorimeter: Heat Capacity of Calorimeter - RF power may be directly converted into heat. Water acts as the load, and RF power may be used to heat an element such as a…
Phase Conversion in Transformer: Three Phase to Two Phase Conversion Transformer (Scott-T transformer or Scott Connection): Phase conversion from three to two phase is needed in special cases, such as in supplying 2-phase electric arc…
Features of Electric Drive System: Before applying advantageously the control principles to electric drive systems to adjust or improve their behaviour as a special case of control problem, it is necessary to have a knowledge…
Programmable Logic Array (PLA) | Block Diagram of PLA: The combinational circuit do not use all the minterms every time. Occasionally, they have don't care conditions. Don't care condition when implemented with a ROM becomes…
Symmetrical Faults on 3 Phase System: Most of the Symmetrical Faults on 3 Phase System on the power system lead to a short-circuit condition. When such a condition occurs, a heavy current (called short circuit…
Active and Passive Satellite: Active and Passive Satellite - Possible communication satellites may be active or passive and the major difference between the two is that whether the communication relay involves passive reflection or an…
Hartley Oscillator using Transistor Analysis: The transistor Hartley oscillator is as popular as Colpitt's oscillator and is widely used as a local oscillator in radio receivers. The circuit arrangement is shown in Fig. 21.16. Hartley…
Overhead vs Underground System: The distribution system can be Overhead vs Underground System. Overhead lines are generally mounted on wooden, concrete or steel poles which are arranged to carry distribution transformers in addition to the…
Current Series Feedback Amplifier Circuit: Current Series Feedback Amplifier Circuit is also known as series-derived series fed feedback. In such a feedback circuit, a part of the output current is made to develop a voltage…
What is Skin Effect and Proximity Effect?: What is Skin Effect and Proximity Effect? - The distribution of current throughout the cross-section of a conductor is uniform only when DC is passing through it. On…
