compensate for it by increasing the supply voltage
/youtube/video/j4u8fl31sgQ?t=90.639999

measure the voltage between these two wires
/youtube/video/j4u8fl31sgQ?t=161.38

bend the wire at the center
/youtube/video/j4u8fl31sgQ?t=183.91

set the current to 100 milliamps
/youtube/video/j4u8fl31sgQ?t=221.64999

change the resistance of my shunt to 10 milliamps
/youtube/video/j4u8fl31sgQ?t=252.16

read it at 1 / 10 length of this wire
/youtube/video/j4u8fl31sgQ?t=259.51001

fold the wires side-by-side

calibrate the length of this wire at 10 amps
/youtube/video/j4u8fl31sgQ?t=486.60001

use a shunt of around 10 kilo ohms
