I've got a simple voltmeter that I'd like to use to measure the power load of some components that I have no idea of. Some are simple (like an LED) and some are more complex sub-assemblies. I'm not sure how to use my voltmeter to measure the mA drawn by the component. I don't seem to be able to just touch the contacts on either side of the component and ground like I do when measuring resistance or voltage levels. Do I need to break the circuit and then use my volt-meter to connect the source to the load? That seems like a lot of trouble and quite difficult to do with soldered-on components and complex wiring harnesses. There must be an easier way. What do I not know?
