Q. Explain with the help of a circuit diagram,the operation of COLPITTS OSCILLATOR.
Oscillator is a circuit used to generate a.c voltage without a.c.input signal.The energy to generate a.c.voltage is supplied from a d.c.source.If the output voltage is a sine wave,the oscillator is called sinusoidal or harmonic oscillator.There is also another type of oscillator called relaxation oscillator which generates voltages or currents which vary abruptly one or more times in a cycle of oscillation.
Conductors with a temperature rating of 75 degrees C are run in an area with an ambient temperature of 55 degrees C. What would be the de-rating factor that should be applied?
Next, let us consider the case of a balanced delta-connected load with impedance of 5 45° supplied by a three-phase, three-wire 100-V system, as shown in Figure (a). We shall dete
