Capacitor Filter:
A capacitor filter is connected directly across the load is displayed in figure. The property of a capacitor is that it permits ac component and blocks dc (direct current) component. The operation of the capacitor filter is for short the ripple to ground but leave dc (direct current) to emerge at output when it is connected across the pulsating dc voltage.
Throughout the positive half cycle, the capacitor charges equal to the peak vale of the transformer secondary voltage, Vm and will try to keep this value since the full wave input drops to zero. Capacitor will discharge via RL slowly till the transformer secondary voltage again gets increases to a value greater as compared to the capacitor voltage. The diode conducts for a period that depends upon the capacitor voltage. The diode will conduct while the transformer secondary voltage becomes much more than the diode voltage. This is termed as cut in voltage. The diode stops conducting while the transformer voltage becomes less as compared to the diode voltage. This is known as cut out voltage.
In this case, 24 simultaneous calls can be put through switch. Generally a 24-outlet Uni-selector is used as a selector hunter. Every one of the 24 outlets is connected to one two-

Given: R 1 = R 3 = 1 k_, R 2 = 100 k_ and k = 0.1 A/V, and step-up transformer turns ratio is 10. a) Find the value of the load resistor RL that would maximize the power
Capacitor-input filter: The capacitor-input filter, as well called pi filter because of its shape which looks like the Greek letter pi, is a sort of electronic filter. Filter
Semiconductor Equations The semiconductor equations that are relating these variables are shown below: Carrier density: n = n i exp (E FN - E i / KT) (1)
What is meant by polling? Polling or device polling is a process which recognizes the device that has interrupted the microprocessor.
Q. Two shunt generators operate in parallel to supply a total load current of 3000 A. Each machine has an armature resistance of 0.05and a field resistance of 100. If the generat
