break — a continuity test. In this test, you pass a small electric current through the wire and measure resistance with an ohmmeter. If the coil is intact, the resistance is a measurable number in the order of 2,500 to 5,000 ohms. If the coil is broken, the resistance will be ...
Although a sensitive ohmmeter can be used to measure Rθ, for more accurate determinations a Wheatstone bridge circuit is used as shown in Figure 42.5. This circuit compares an unknown resistance Rθ with others of known values, R1, and R2 being fixed values and R3 being variable. Galvano...
