Earlier we noted, in Equation 25.3.4, that the current in linear sweep voltammetry is proportional to the slope of the concentration profile. The current is also a function of other variables, as shown here for the reduction of Fe (CN)3 − 6 to Fe (CN)4 − 6. i = nFAD([Fe(CN)3 − 6]bulk − [Fe(CN)3 − 6]x = 0) δ.

Current limiting is the practice of imposing a limit on the current that may be delivered to a load to protect the circuit generating or transmitting the current from harmful effects due to a short-circuit or overload. The term "current limiting" is also used to define a type of overcurrent protective device. According to the 2024 NEC/NFPA 70, a current-limiting overcurrent protective device is defined as, "A device that, when interrupting currents in its current-limiting range, reduces the c… Nettet8. jan. 2014 · imbaine13.
