### Indirect Measurement of the Current Draw of a Device

by MrAl Published on 15th October 2012 09:00 AM     Number of Views: 2021
Sometimes we want to know the current draw of a device for various reasons. One reason would be to estimate the run time of the device when it is running on batteries. It is often very inconvenient to try to break the battery connections and insert a current meter or sense resistor, so here is an alternate method that does not require breaking the current flow.
