Was asked one today that I could not answer.
Appreciate any knowledge from any one who knows, has monitoed current when a fuse breaks, or opinion.
.
Calculations for the current that a fuse must successfully break.
My friend argues that including the fuse normal resistance in the calculation as a current limiter is inappropriate because as the fuse breaks, the plasma, molten fuse, may have significantly lower resistance. Hence it must break the current possibly equivalent to the circuit without the fuse resistance.
.
Seems plausible.
.
Anyone know this? Or a standard for such calculation? Or behaviour of current at that point in time?
Thanks in advance.
