Current limiting is the practice in electrical or electronic circuits of imposing an upper limit on the current that may be delivered to a load with the purpose of protecting the circuit generating or transmitting the current from harmful effects due to a short-circuit or similar problem in the load. This term is also used to describe the ability of an overcurrent protective device (fuse or circuit breaker) to reduce the peak current in a circuit, by opening and clearing the fault in a sub-cycle time frame.

Famous quotes containing the words limiting and/or current:
“I am truly free only when all human beings, men and women, are equally free. The freedom of other men, far from negating or limiting my freedom, is, on the contrary, its necessary premise and confirmation.”
—Mikhail Bakunin (1814–1876)
“We all participate in weaving the social fabric; we should therefore all participate in patching the fabric when it develops holes—mismatches between old expectations and current realities.”
—Anne C. Weisberg (20th century)
