What is the ideal value of ripple factor?
Zero
How do you measure amplitude of a ripple?
Most true RMS voltmeters can measure the value of a ripple voltage on top of a DC supply, when you place it in AC mode. You can also place a small capacitor in series with a DC voltmeter and that would measure the ripple. The real way to do this, because ripple voltage is not sinusoidal, is to use an oscilloscope, particularly if you want the peak values.
How do you save energy with power factor correction?
Power-factor correction doesn't save energy. Power-factor correction is used to reduce that magnitude of the current drawn from the supply in order to minimise the cross-sectional area of the supply conductors and associated equipment -thus keeping down the cost of the supply circuits which are owned by the supply company. Power-factor correction doesn't apply to homes, but only to larger commercial or industrial premises. The electricity supply company will negotiate a value of power factor for the load, and apply a penalty charge to the customer if his load is not kept within that agreed value.
Why Voltage x Current do not equal rated power?
In an AC system power is equal to Voltage x Current x Power factor. Power factor is not constant and depends on the type of the load. Ideal value of the Power factor is 1, where as practically remains less then 1.
What is the Ideal value of Stability factor?

How do you calculate the capacitance value of filter capacitor for full-wave bridge 12VDC power supply?
THe Filter capacitor value depnds on the maximum current I of the Power supply , Switching frequency and the permissible ripple C= (I * (1/2f ))/ ( V * %Ripple) - for a full wave rectifier C= (I * (1/f ))/ ( V * %Ripple) - for a Half wave rectifier Where C= Capcitance in Farads I = Current in Amps f = Switching Frequency V = Nominal voltage in this case 12 V Reji J Thoppil
Methods of calculating Ripple voltage in supply without using oscilloscope?
Measure AC voltage with multimeter. It is easiest way to check how big ripple is. There is no way to 'calculate' value.
Definition of ripple factor?
Also called "domino effect" domino effect: -noun the cumulative effect that results when one event precipitates a series of like events. ~Dictionary.com the value of ripple factor tells how much the output (of a particular devise) varies from the ideal (or theoretical) value.
What is ripple factor?
Ripple factor (γ) may be defined as the ratio of the root mean square (rms) valueof the ripple voltage to the absolute value of the dc component of the output ...
How do you get the buzz out of the Magnivox radio 1970s?
Here's one possibility ... no guarantee: Radios of that era used large-value electrolytic capacitors in their power supply filters. These capacitors can deteriorate over time, allowing AC-ripple out of the power supply, which is then clearly audible in the audio stages. Take the radio to a TV-repair shop or a friend familiar with electronics construction, and ask them to replace the electrolytic capacitors in the power supply.
What is the function of a filter capacitor in a power supply?
A: The function is to change the pulsating DC into a smooth DC by removing the peak changes. The results are very little AC variation riding on top of the DC value or simply referred as ripple.

What is the ideal value of vswr?
The ideal value of VSWR is 1 (one), which means that full power which has been arrived to the antenna is emitted to the air. In reality it is always more than 1, which means that some part of power reflected from antenna to the transmission line.
