Mrs. Bailey was important in the educational journey that carried me through school and into my profession. Until I joined her class, I hadn’t believed in my ability as a writer. She 1 (persuade) me to join the poetry society and lit in me a fire for literature. She recognised 2 (I...

Test failure: Differences in the bridge balance measured values exceed 1% or the input and output resistances exceed 3 kilo-ohms. This happens due to electrical component failures or an internal short circuit. The cause of these problems is generally lightning strikes (overvoltage), excess temperatu...
The most common type is the standard circuit breaker, which safeguards against overloads and short circuits by automatically cutting off the electrical flow when excessive current is detected. Ground Fault Circuit Interrupters GFCIs are another vital type, predominantly used in areas prone to moisture...
Current measurement shunts, or current shunt resistors, are resistors placed in the circuit for the purpose of measuring the current that flows across the shunt. These are fairly common electrical components and exist for a variety of applications. Sizing a shunt will be based on measurement curren...

Replace the fuse, or reset the breaker. If the circuit holds, it"s possible something you disconnected is faulty. Check for short circuits or other problems. If there"s no evidence of electrical fault in the fixtures, the problem may be too much current draw for the circuit to handle. In...
As a result, unlike neutral or hot wires, “ground” wires do not carry any electrical current under normal conditions. They are only used if a ground fault occurs. Ground faults are abnormal electrical current flows. For example, suppose your house is struck by lightning. This would almost ...
