What do you mean by filtering output voltage?
power filter diagram
What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
What determines the output voltage and the current of a transformer?
The ratio of output windings to input windings determines the ratio of output voltage to input voltage. The ratio of current is the inverse.
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.
Why might the unloaded output voltage of a transformer be higher than its rms of 12.6v?
Because the windings of transformers have resistance, the primary and secondary currents will cause voltage drops. To compensate for the drops, the transformer may have been designed to have a higher than specified output voltage when there is little or no output current. The no load output voltage typically is only slightly greater than the specified voltage. Before measuring the output voltage, measure the input (line) voltage. If it is not as specified for the transformer, calculate its effect on the output.

If vm is maximum peak voltage of rectifier outputthis rectifier output is connected to the capacitor filterwhat will be the approximate dc output voltage to the capacitor filter?
It should be the rms value of your supply.
Output voltage of half wave rectifier without capacitor filter is less or more than rectifier with capacitor filter?
less
Why cant capacitor filter connected in series to load?
in output is pulsetting voltage remove the pulses to use the capacitor this passes the pure voltage to the load
What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
What is the difference between a step down chopper and a buck converter?
Choppers are dc - dc converters, on the basis of output voltage level step down chopper is used for output voltage less than input one. A buck converter is a step down chopper with a LC filter at the output end in order to reduce the voltage ripples.
What causes increase of the output of a generator that should be 220 volt to 400 volt?
It sounds like the field voltage potentiometer is not working or has been turned up. Try turning it down and see if the output voltage goes down with it. If it doesn't then the voltage regulator is not working as the field voltage is regulated from the regulator.
What is a dimmer?
A dimmer reduces the voltage to a light so that the current is reduced, which causes the bulb to have a reduced lumen output.
Is it the value of input voltage equal the value of output voltage?
No. There are several factors that may affect the output voltage. For instance: Resistors, Transformer, Voltage regulators and others that can control the output voltage to a certain level.
How does an alternator know how much voltage output?
Output of the alternator is controlled by the voltage regulator.
How can be a DC voltage source output voltage made half of its output voltgae?
By using something called a voltage divider.
What determines the output voltage and the current of a transformer?
The ratio of output windings to input windings determines the ratio of output voltage to input voltage. The ratio of current is the inverse.
