    Ammeter Voltmeter
AI Thread Summary
An ammeter should be connected in series to measure current, as connecting it in parallel can create a short circuit, potentially damaging the device. Conversely, a voltmeter is designed to be connected in parallel to measure voltage across two points; connecting it in series will not provide a voltage reading since the voltage at both points would be the same. The discussion emphasizes that an ammeter acts like a short circuit while a voltmeter functions as an open circuit. Proper connections are crucial for accurate measurements and to avoid damaging the instruments. Understanding these principles is essential for effective circuit analysis.

first if i were to connect an ammeter i would connect it in a series correct?
if i connect the ammeter in parallel what would happen?


second if i were to connect a voltmeter i would connect it in parallel?
if i connect the voltmeter in series what would happen?

An ammeter is basically a short circuit, and a voltmeter is an open circuit. Can you answer the questions for us now?
 
umm if you place voltmeter in series you would measure not voltage because, the voltage at two points are the same..

im not sure about ammeter tho...

Normally you place the voltmeter across whatever two points you want to measure the difference in voltage. You place an ammeter in series with a circuit branch to measure the flow of current through that branch.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
