Voltmeter Definition and 152 Threads

a dual-range d.c. voltmeter has a common negative terminal and two positive terminals, one of which gives full deflection of 10V, and the other of full deflection 3V. Given that the voltmeter resistance btw negative terminal & the other of full deflection of +3V is 1000 ohm. what is the...

I took some measurements for a Physics lab and don't recall whether the Voltmeter I used reports the peak voltage or rms voltage. I need rms voltage to calculate the rms current. Can anyone tell me what the norm is for voltmeters: peak or rms? To divide by the [squ]2 or not to divide by the...
