3.5 Measuring Voltage and Current
When working with actual circuits, you will often need to measure volt-
ages and currents. We will spend some time discussing ... Lower resistances are
difficult to measure on a standard Wheatstone bridge because of thermo-
electric voltages generated at the junctions of dissimilar metals and
because of thermal heati...

most convenient to choose the capacitive voltage; for RL circuits, ... the same form (compare Eq. 7.48
