How is a resistor measured

WebRemember, a resistor is a non-polar device, so you don’t need to worry about which probe is to be connected to which side of the resistor. You can always confirm this statement … WebThe voltage is measured with a voltmeter, which must be placed across the resistor (in parallel with the resistor). The current is measured with an ammeter, which must be in line with the resistor (in series with the resistor). Figure 9.19 The experimental set-up used to determine if a resistor is an ohmic or nonohmic device.
