Experiment 15: Ohm’s Law
www.phy.olemiss.eduVoltmeters are connected in parallel to resistive elements in the circuit so that they measure the poten-tial di↵erence across (on each side of) the element. The ideal voltmeter has infinite internal resistance. Our voltmeters have approximately 10 M⌦(10⇥106 ⌦) internal resistance so that only a minuscule amount of

Most ADCs today have a built-in sample-and-hold function, thereby allowing them to process ac signals. This type of ADC is referred to as a sampling ADC. However many early ADCs ...
