To measure current you have to connect multimeter in series with the load and the battery. The current should flow through the multimeter to the load.
First set the multimeter knob in current measuring position. Then connect the red and black wires comming from the multimeter in series with the load. Then you will notice the current flowing through the load or device in the screen of multimeter.
Current is the flow of electrons. So to know the flow, multimeter or ammeter should be in series with the device and the battery.
You can measure both ac current and dc current (I) with the help of a multimeter.
