How do you measure DC amp output from rectifier unit?
You can use a DC ammeter.
Can moving coil galvanometer be used to detect ac in a circuit give reason?
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.
How short circuit current measure?
In shortg circuit current is infinitive.
What are applications of OHM METER?
It measures resistance in a component or circuit to determine if there is a break in that circuit or component. If there's no resistance, it means there's a break, as no electrical current is passing through.
Why does not it matter where you measure the current in a simple circuit?
The current measured at any point in a simple circuit will be the same because current is the measure of electron flow through a circuit. The current flowing through any branch of any circuit (or an entire simple circuit) will always be the same at any point.
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.
How do you know when a rectifier is bad?
(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.
What quantity is hertz used to measure?
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.
How much HZ are in a mile at the speed of 30mph?
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.
What is frequency's unit of measure?
Hertz, hz= 1/second is the unit measure of frequency.
Is the measure of loudness frequency or decibels?
The decibel is a measure of loudness. Frequency is related to pitch.
