Electrical (A6)第 68 / 120 题
An open in a series circuit will cause:
a.Increased current flow
b.No current flow in the circuit
c.Higher voltage at the load
d.Reduced resistance
解析
A series circuit has only one path, so an open anywhere stops all current and the load will not operate. Voltage will be present up to the open point when tested. Locating the open often uses a test light or voltmeter along the circuit.
