Abstract

In Tasks 2 and 3 of previous chapter’s laboratory (diode and transistor temperature sensors), we measured V ab across the 1 Ω resistor to evaluate the current. We did not measure V a and V b separately and make a subtraction, as both are on a scale of several volts (measured in 0–20 V scale), while their difference is only in millivolts (measured in 0–200 mV scale). If you have a DMM, you can connect one of its leads to the position a and the other to b to measure this tiny voltage drop. This is not really possible if you plan to develop a stand-alone sensing device.
