What is the formula to find reading of ammeter Answers.com
26/07/2017 · Consider using a "clamp-on" ammeter. Ideal for the homeowner, this meter were to be used to measure current through a 4700 ohm resistor across 9 Volts DC. To do this, insert the black probe into the "COM" or "-" jack and insert the red probe into the "A" jack.... Read and study your ammeter manual. Not all ammeters have the same scale calibration or the same types of control knobs or range settings. Pay special attention to any safety instructions or warnings that are listed in your manual.
Why we want to convert a voltmeter to an ammeter or vice
Now the ammeter which converted to a voltmeter should have the full scale read out when 5 volt is connect to it. This approach assumes the ammeter has zero internal resistance. In reality all ammeters will have some resistance.... You read the bottom scale to get the amperes - that is what the meter is actually reading. However, if the load is 50 ohms, precisely, then the square of the number of …
How to make an ammeter All About Circuits
Read and study your ammeter manual. Not all ammeters have the same scale calibration or the same types of control knobs or range settings. Pay special attention to any safety instructions or warnings that are listed in your manual.... 7/10/2017 · Goodmorning, everyone. Please can anyone help with how to read this analog ammeter? Have being trying to see if I could use it as an ammeter during my battery rebuild processes, and I'm kinda getting frustrated not able to read it.
ANALOG VS. DIGITAL METERS Ultimately, your diagnosis of vehicle electrical system problems will come down to using a voltmeter, ammeter, or ohmmeter to pinpoint the exact location of the problem. There are two types of each meter—analog and digital. Analog meters use a needle and calibrated scale to indicate values. Digital meters display those values on a digital display. This chapter will... A needle attached to the coil allows to read the current corresponding to that angle. If you want to measure voltage, you can put a resistor in series with the instrument. The voltage causes a certain current, which is then measured.

- There’s many different ways of measuring current. If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer.
- Connecting the multiplier to a battery through different resistors and an analog ammeter will demonstrate that magnetic needle moves synchronously with the ammeter’s pointer, which means that the multiplier also measures current.
- Ammeters,Voltmeters,andGalvanometers An ammeter (the name is a contraction of ‘ampere-meter’) is a device for measuring the electric current through a wire or a circuit element.
