WebCSF shunts are commonly utilized in the management of hydrocephalus. In fact insertion of CSF shunts has become one of the commonest procedures in the modern neurosurgical practice [11]. To achieve a long term internalized CSF diversion, CSF shunts generally consist of two tubes, one of which is placed More generally, the term shunt can be used for a component connected in parallel with another. ... All shunts have a derating factor for continuous (more than 2 minutes) use, 66% being the most common, so the example shunt should not be operated above 330 A (and 50 mV drop) longer than that. See more In electronics, a shunt is a device that creates a low-resistance path for electric current, to allow it to pass around another point in the circuit. The origin of the term is in the verb 'to shunt' meaning to turn away or follow a different … See more In photovoltaics, the term is widely used to describe an unwanted short circuit between the front and back surface contacts of a solar cell, usually caused by wafer damage. See more Capacitors are used as shunts to redirect high-frequency noise to ground before it can propagate to the load or other circuit components. See more Where devices are vulnerable to reverse polarity of a signal or power supply, a diode may be used to protect the circuit. If connected in series with the circuit it simply prevents reversed current, but if connected in parallel it can shunt the reversed supply, … See more One example is in miniature Christmas lights which are wired in series.
