  • Chapter 12: Fundamentals of Electricity & Electronics › Basic Circuit Analysis & Troubleshooting › Troubleshooting Shorting Faults in Parallel Circuits

    Troubleshooting Shorting Faults in Parallel Circuits As in a series circuit, a short in a parallel circuit usually causes an open circuit by blowing the fuse. But, unlike a series circuit, one shorted component in a parallel circuit stops current ... should be accomplished with an ohmmeter. But, as in the case of checking for an open resistor in a parallel circuit, a shorted resistor can be detected with an ohmmeter only if one end of the shorted resistor is disconnected…

    which two of more electrical resistances or loads are connected across the same voltage source is called a parallel circuit. The primary difference between the series circuit and the parallel circuit is that more than one path is provided ... current in the parallel circuit. Each of these parallel paths is called a branch. The minimum requirements for a parallel circuit are the following: • A power source • Conductors • A resistance or load for each current path • Two or more paths…

    voltmeter scale. When it is connected across the shorted resistor, the voltmeter reads zero. Troubleshooting Open Faults in a Parallel Circuit The procedures used in troubleshooting a parallel circuit are sometimes different from those used in a series circuit. Unlike ... series circuit, a parallel circuit has more than one path in which current flows. A voltmeter cannot be used, since, when it is placed across an open resistor, it reads the voltage drop in a parallel branch. But an ammeter…
