Magnetically Induced Emf and Force: Magnetically Induced Emf and Force - Faraday's law of induction, which is the integral form of the fourth Maxwell's equation, is given as The integrated form of Eq.(2.15) for a…
Wein Bridge Oscillator using Op Amp: The Wein bridge is an ac bridge that balances only at a particular supply frequency. In the Wein Bridge Oscillator using Op Amp (Fig. 16-10), a Wein bridge circuit…
EEPROM (Electrically Erasable Programmable Read Only Memory): Electrically Erasable Programmable Read Only Memory (EEPROM) also use MOS circuitry very similar to that of EPROM. Data is stored as charge or no charge on an insulated…
Bipolar Junction Transistors (BJTs) Interview Questions and Answers: 1. Explain why BJT is a polar device. Ans. Since both of the charge carriers (electrons and well as holes) are involved in current flow through a BJT…
Relay Classification in Power System Protection: There are various types of Relay Classification in Power System Protection. Normally the actuating quantity is an electrical signal, although sometimes the actuating quantity may be pressure or temperature.…
Dual Gate MOSFET - N Channel Depletion Type MOSFET: Cross view of a dual-gate N-channel depletion type MOSFET is shown in Fig. 13.93. It acts as if two FETs are connected in series, as is…
Reversible Drive using Field Reversal: A Reversible Drive using Field Reversal can be realised as shown in Figs. 4.83 and 4.84. In Fig. 4.83, the armature is fed from a two quadrant converter with change…
Planar Triode Construction: Planar Triode Construction - A short transit time is essential if grid loss and noise are to be minimized, as is the reduction of internal capacitances and inductances. Also, since coaxial resonant…
Medium Transmission Line: For lines more than 100 km long, charging currents due to shunt admittance cannot be neglected. For lines in range 100 km to 250 km length, it is sufficiently accurate to lump…
Per Unit System: While carrying out the analysis of electrical machines (or electrical machine systems), it is usual to express voltage, current, VA and impedance in Per Unit System (or percentage) of the base or…
