How does a DC generator used as a tachometer work?
Here we will just connect DC generator shaft with motor's rotating spindle. Now connect voltmeter across dc gen. and just calibrate voltmeter in terms of rpm. If you have worked with micro-controllers then it will be very easy using it's ADC input.
What will happen if DC voltage is measured using AC voltmeter?
You will not get a measurement. depending on what kind of measuring device you use the socket could begin to smoke and the voltmeter will fly out (happened to me).
Where can you buy a dc voltmeter?
