occurs in the parallel portion of a series-parallel circuit, as shown in Figure 12-188, part of the circuit continues to function. In this case, the lamp continues to burn, but its brightness diminishes, since the total resistance ... decreased. 3. If the open occurs in the branch containing the lamp, as shown in Figure 12-189, the circuit continues to function with increased resistance and decreased current, but the lamp does not light…

battery continues to be used, the voltage changes, thus requiring an adjustment. The meter should be “zeroed” before each use. To check the value of a resistor, the resistor must be disconnected from the circuit. This prevents any possible damage ... ohmmeter, and it prevents the possibility of any inaccurate readings due to the circuit being in parallel with the resistor in question. [Figure 12-172] Continuity Checks In many cases, the ohmmeter is not used for measuring the resistance…

circuit that is not broken or does not have an open. • Discontinuity—the opposite of continuity, indicating that a circuit is broken or not continuous. Voltage Measurement Voltage is measured across a component with a voltmeter or the voltmeter position ... some resistance and will shunt some of the current. This has the effect of changing the characteristic of the circuit because of this change in current. This is typically more of a concern with older analog type meters. If there…
