... V; (b) 166.67 mA; (c) 347.22 mW. 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...

... responses of circuits, it may help to follow these steps: 1. Identify the variable of interest for the circuit. For RC circuits, it is most convenient to choose the capacitive voltage; for RL circuits, ... the same form (compare Eq. 7.48 and Eq. 7.50). To generalize the solution of these four possible circuits, we let x(t) represent the unknown quantity, giving x(t) four possibl...
