Why does my multimeter show a higher current with lower sensitivity when measuring AC current?
In the 200 setting, shouldn't you have the test lead in the mA socket, not the 20A socket. The 200 is just 200mA, not 200A.

How can I achieve full scale deflection on a 30 A ammeter with a 5 V voltage?
After looking at the second photo you have added, it looks like the shunt resistor that would be required for 30A FSD may have originally been external to the meter and that the meter really only real …

Why am I getting very different measurement results on a breadboard?
It looks like you have the + and - shorted out in the same track on the breadboard. The breadboard track will probably be getting hot. It is not a good idea to put an ammeter directly across the pow …

At which amperage will 2 x 100A fuses mounted onto a dual fuse holder blow?
If one of the circuits draw enough current to blow its fuse, the other fuse would be unaffected. … As @Neil_UK stated in the comments - "They are rated to carry 100A for some 1000s of hours, and will break at some larger current, after some typical time (maybe 200A takes 10s to blow it, depends on the …
