If we deal with power or capacity measurements, we need two multimeters, one for volt and the second one for ampere. And if we want to measure efficiency, we need four multimeters. In earlier videos, I used small all-in-one meters for that purpose and got the request to show how I built them. So today we will build small and cheap meters which measure volt, ampere, power and capacity at the same time. For around 15 dollars each.
