How do you determine the size of acapacitor in a rectifier circuit?
ANSWER In rectifiers for power supplies, the capacitor size is determined by the allowable ripple on the output. This can be determined by the rate at which the capacitor is drained. Specifically, this rate is the current drawn from the capacitor. Assume a half wave rectifier made from four diodes. For part of the cycle, the output current is supplied by the rectifier diode. This is also when the capacitor is charged. While the rectifier is not supplying current -- when the input waveform has dropped below the output voltage -- the capacitor must supply the current. Then, as the input waveform rises above the capacitor voltage, the rectifier supplies the current to charge the capacitor and the output circuit.
Output voltage of half wave rectifier without capacitor filter is less or more than rectifier with capacitor filter?
less
What are the simple applications of bridge rectifier?
A bridge recifier is a full wave rectifier. It takes each part of the AC waveform, rectifies it and adds them together, giving a smoother output compared to a half wave recifier. They are used in simple power supplies, using a mains transformer, a bridge rectifier and a smoothing capacitor. Further regulation can then be added for stable power supplies.
What is a rectifier circuit?
The Rectifier is an electronic device, which converts an AC waveform(Usually a Bi-directional waveform with Zero Average value) to a Pulsating DC waveform (Uni-directional waveform with Nonzero Average value). As AC wave (Sinusoidal) has two half cycles, namely - Positive Half cycle & Negative Half cycle If a Rectifier does it's operation only in one half of the cycles, it is known as Half Wave Rectifier. Similarly, If a Rectifier does it's operation in both the half cycles, it is known as Full Wave Rectifier.
What effect does an open diode have on the output voltage of a half wave rectifier and on a full wave rectifier?
An open diode will result in no output from a half wave rectifier, and an open diode will cut the output of a full wave rectifier in half.

What is the effect of an RL circuit in half wave rectifier?
The effect of an RL circuit in half wave rectifier is that the voltage output wave forms for current and voltage will be modified .
What effect does an open diode have on the output voltage of a half wave rectifier and on a full wave rectifier?
An open diode will result in no output from a half wave rectifier, and an open diode will cut the output of a full wave rectifier in half.
What is the frequency of ripple components in the output of capacitor filter?
It depends on whether or not it is a half wave or full wave rectifier. For a single phase 60 Hz rectifier, a half wave rectifier will be 60 Hz while a full wave rectifier will be 120 Hz. A three phase full wave rectifier will be 360 Hz.
When a 60 Hz voltage is applied to the input of half wave rectifier what is input freequency?
The relationship of the input frequency and output frequency in a half-wave rectifier is one-to-one.(For full-wave, its one-to-two.)The shape won't be the same, as the rectifier will only pass alternate half-cycles, but the apparent frequency will be the same.

Is any effect of capacitor on half wave rectification?
yes
Comparision between half wave and full wave rectifier?
A half wave rectifier conducts on every other cycle. The output is a train of half sine cycles, at a period equal to the input period. At 60 Hz, the period is 16.7 ms. Each half cycle (8.3 ms) will be interleaved with periods (8.3 ms) of no voltage. If you filter the output with a capacitor, you get DC - at no load, the DC will be the peak value less the forward bias voltage of the diode - at some load, the DC will fluctuate between that peak value and some value dependent on the size of the capacitor and the current draw. Again, the period (of this nearly sawtooth waveform) will be the input period. A full wave rectifier conducts on every cycle. The output is a train of half sine cycles, at a period equal to half the input period. At 60 Hz, the period is 8.3 ms. Each cycle (8.3 ms) will be connected to the preceding cycle with no intervening delay. Each cycle will pulse in the same direction, instead of in alternating directions. If you filter the output with a capacitor, you get DC - at no load, the DC will be the peak value less the forward bias voltage of the diode - at some load, the DC will fluctuate between that peak value and some value dependent on the size of the capacitor and the current draw. Again, the period (of the nearly sawtooth waveform) will be half the input period. Since the full wave output waveform is twice the frequency (half the period) of the half wave output, the capacitor can be about half its required value for the half wave circuit in order to achieve the same level of filtering.
What is the effect in output for changing input frequency in halfwave rectifier?
if filtered and loaded the average DC voltage will increase and the ripple AC voltage will decrease, but the peak voltage is unchanged. this is because the filter capacitor has less time to discharge into the load.if unfiltered or unloaded the voltage cannot change. unfiltered the waveform just follows the half cycle of the input. if filtered but unloaded the output is DC at the peak voltage of the input AC.
