Self-inductance and the induced e.m.f
Inductance is the name given to the property of a circuit whereby there is an e.m.f induced into the circuit by alter of flux linkages produced by a current change. When the e.m.f is induced in the similar circuit as that in which the current is changing, the property is known as self-inductance, L.
The mechanical power produced at the armature of a motor is: P = T a . (power is in watts if torque is N.m and in rad/sec). Some of this will be lost due to friction and
Q. What is thermal runaway. The problem of self heating arises due to dissipation of power at the collector junction. The leakage current ICBO is extremely temperature dependen
Problem (a) Figure gives the basic circuit of the diode limiter. Assuming that the diodes are ideal sketch and annotate the waveforms of the input voltage vi(t) and the load
To have the same value of P e , show that E b /N 0 in a coherent-ASK system has to be twice that in a coherent PSK system.
Thyristor The name thyristor is derived bya combination of the capital letters from thyratron and translstor. This means that thyristor is a solid state device like a
Q. How can a JFET be used as a constant current source? Explain from the drain characteristics. As the VDS voltage is increased from 0 to a few volts, the current will increase
Q. The effective area of a dipole is given by A e =0.13λ 2 . Find the effective area of a half-wave dipole at 3 GHz.
Q. What do you mean by Negative Clamper? During the positive half cycle the diode conducts and acts like a short circuit. The capacitor charges to peak value of input voltage V
Role of Bureau of Energy Efficiency The role of the Bureau of Energy Efficiency is to: Ready standards and labels of appliances and equipment; Develop a list
The corners of wedge-shaped block are A(0,0,2), B(0,0,3), C(0,2,3), D(0,2,2), E(-1,2,2) and F(-1,2,3) and the reflection plane goes the Y-axis at 450 between (-X) & (Z) axis. Calcu
