Manual multimeter users should look for the correct range. If you want to measure higher amperages, youll need to use clamp meters, which will need a different set of instructions. The measuring should be similar to measuring a 220v circuit in that measuring only one leg will give you the 220v flow for the entire house, but that would not be showing the 110v flow. 1. Youll need a multimeter capable of measuring current to measure amps accurately. In this case we can see that our resistor has a value of 220 Ohm. Then connect the black wire to the same row as the LEDs remaining leg. In that case, you should seek assistance from a qualified electrician to ensure your safety and prevent any damage to the electrical system.
