Maybe a daft question but can I use a resistor in a circuit to act like a fuse. The circuit is powered by a 4.2V LIPO cell and the maximum current drawn (or should be) at 4.2v is 400mAh. Can I put a resistor into this circuit to act as a fuse if the current drawn exceeds 500mAh.
It's not that I am to tight to go and buy a fuse but I need this circuit sent off by tonight and I don't have any fuses at hand?
I was once in the presence of a cleverer man than me and he pointed out that a resistor had blown in a circuit and he said "The resistor had acted like a fuse in the circuit by burning out before anything else did". This got me thinking!
Thanks..
