### How could you measure ripple frequency to determine if a diode were open in a bridge rectifier circuit?

Measuring ripple frequency would determine if a diode were open
in a bridge rectifier circuit because the ripple frequency is
normally twice the input frequency in a functioning full wave
bridge rectifier. If one diode were open, the ripple frequency
would only be the input frequency.
Note: This is true for single phase or bi-phase operation. Three
phase operation is more complex, but still doable - You would
expect three times input frequency in normal state, and two times
(asymmetric) with one open diode.

### What is ripple frequency of 50 Hz 3 phase full ac supply?

A single phase half wave rectifier outputs ripple the same
frequency as the input.
A single phase full wave rectifier outputs ripple fundamental
twice the input frequency (assuming balanced recitfiers).
A three phase full wave rectifier outputs ripple fundamental six
times the input frequency. So 50 Hz input would yield 300 Hz
ripple.

### 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.

###### Asked in Electronics Engineering

### How the frequency is related to rectifier circuit?

Your question is incomplete. In order to answer it I must do so
based on an assumption.
The assumption being that the frequency to which your refer is
that of the ripple on the rectified voltage.
There are two basic types of rectifier, half wave and full
wave.
A full wave rectifier conducts on only one half cycle of the
a.c. input. The ripple will therefore be at the frequency of the
a.c.
A full wave rectifier conducts on both half cycles of the a.c.
input. The ripple will therefore be at twice the frequency of the
a.c.

### What is the ripple frequency of a half wave rectified 3 phase 50Hz supply?

you can't have half wave rectified polyphase AC power, unless
you are using only one of the phases. however with only one diode
from each phase of three 50 Hz phases the ripple frequency is 150
Hz, with two making a full three phase bridge the ripple frequency
is 300 Hz. perhaps that was what you meant.

### What is a ripple?

Ripple is the oscillations that can arise in a circuit when a
signal changes suddenly. It stems (in analog circuits at least)
from stray capacitances and inductances forming a resonator.
Answer--
Ripple can refer to:
* Ripple (charitable organisation)
* Ripple effect, the socio-educational phenomenon
* Ripple (electrical), residual unwanted variations following ac
to dc conversion
o Frequency domain ripple, the ripple of a filter's insertion
loss
* Ripple (fluid dynamics) for capillary waves
* Ripple, Kent, a village in Kent, England
* Ripple, Worcestershire, a village in Worcestershire,
England
* Ripple marks, as identified in sediments and sedimentary
rocks
* Ripple monetary system
* Ripple (wine)

### What is frequency meter?

###### Asked in Physics

### Can you make a sound inaudible by another sound with the same frequency?

The same frequency and the same amplitude but inverse. This
would be a tricky accomplishment, not sure if it can be done
perfectly but I'm sure it can be done partially. To visualize this,
you can throw rocks in a pond and watch the ripples and imagine two
ripples the same size and frequency but of opposite polarity (that
is, the peak of one ripple hits the trough of the other ripple such
that they cancel each other out). If you have a method of doing
this perfectly, please let me know (we could get very rich ;-)
