[edit] Drop in voltage

Hello, can someone add how to compute the drop in voltage when we add a voltmeter ? It would be very nice for me.--Youssef 15:37, 14 July 2005 (UTC)

[edit] Voltmeter/currentmeter

Could someone explain how it is possible to convert a current meter to a volmeter via a resistance?

.......VOLTMETER>>>>> Why is a voltmeter connected in parallel in a circuit? BUBBLES

Because if it were connected in series the current would flow through the voltmeter and you would get the voltage drop due to the resistance of the voltmeter, not the circuit. eg. say you had your voltmeter connected in parralel over a switch and were measuring votlage applied through the switch. When closed the current would take the path of least resistance, this being the switch which has no resistance and therefore the voltage drop reading is zero. If the switch was open the current would be forced to travel through the voltmeter which has very high resistance and the reading would be that of the applied voltage.

DVM -- Can anyone tell me what the 4th connection point is on a Digital Volt meter and how it is different than the DVM that only hast 3 connections.

[edit] Electromechanical movements

I was redirected here from moving coil meter which I need to illustrate another article...how about a d'Arsonoval movement diagram? I know, I know...if I want one I have to draw one....--Wtshymanski (talk) 17:00, 22 November 2007 (UTC)
