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.
To measure the current in the circuit an ammeter is used and it is connected in series
Frequency response is the measure of the frequency of the output a device gives in response to a stimulus that it receives. The frequency response is a characteristic of the device.
a meter uses its own supply to measure resistance. you dont have to remove the resistor from the circuit but you must isolate it from the circuit supply to get an accurate reading.
The impedance of an electric circuit is the measure of the opposition presented by a circuit when the current and voltage is applied.

(1) A basic check of a simple electrical rectifier (diode) requires the application of an ohm meter (an electrical resistance measurement device). A digital ohm meter (digital multimeter or DMM) is easier to use than the conventional dial (analog) type of meter. (2) The rectifier must be disconnected from the circuit to be assured of an effective test. (3) Measure the resistance of the rectifier from one terminal to the next. (4) Switch the meter test leads to measure the rectifier in the opposite direction. Do not to touch the electrical conducting parts of the meter leads or the terminals of the rectifier with your fingers or you may cause a false measurement. (5) Usually an effective rectifier has at least a 10 to 1 ratio of resistance as measured one direction versus the other.
One would measure hertz by using an analog ammeter. Hertz can be measure in kilohertz. Hertz is the unit used to measure frequency. Any instrument that measures frequency can be used to measure hertz. 1 hertz is 1 cycle per second. By radio frequency.
Hertz is a measure of frequency, and has nothing to do with speed problems.Hertz is a measure of frequency, and has nothing to do with speed problems.Hertz is a measure of frequency, and has nothing to do with speed problems.Hertz is a measure of frequency, and has nothing to do with speed problems.
Hertz, hz= 1/second is the unit measure of frequency.
The decibel is a measure of loudness. Frequency is related to pitch.
You can use a DC ammeter.
frequency meter is used to measure the frequency of unknown frequency signal.
Hertz, hz= 1/second is the unit measure of frequency.
Moving coil galvanometer is used to detect unknown resitance of the both ac or dc circuits :)deepak instrumentation engineerAnswerA 'galvanometer' is simply an instrument that detects and measures small currents; 'moving coil' describes its operating principle. A moving-coil galvanometer is a d.c. instrument; if subject to a.c., then it will simply vibrate as it will not be able to respond the the frequency (unless the frequency is very low, in which case, it will sweep back and forth in step with that frequency).The moving-coil principle is applied to other instruments, and can be used in the construction of multimeters. In the case of a multimeter, a rectifier circuit is incorporated so that it can be used to measure a.c. currents and voltages.

A capacitor alone doesn't have a frequency. The combinationof a capacitor and an inductor (coil) has.-- Read the value of capacitance printed on the capacitor, or measure it. Call it ' C '.-- Read the value of inductance printed on the coil, or measure it. Call it ' L '.The resonant frequency of the combination of those two components isF = 1 / (2 pi) sqrt(L C)
