Hi. I have a doubt regardng fuse. Imagine that i have a equipmnt which is working at 12v Dc / 3 amps. In this equipmnt power cable have positive (in tis wire having 5amps fuse)and negative terminal. Then i connected the equipment with 12v Dc 30 Amps Power supply. According to fuse behaviour its dependent on current. in this case the supply from power supply is 12 v 30 amp which is passing to through the positive and negative terminal. But how the fuse in positive terminal is still working?according to the fuse behaviour it has to blown. Pls clarify
