How much Current does it Take?
The first diagram below shows how to use the DMM to measure the current that an LED needs. The second diagram shows how to measure the current that a motor uses.
Using the DMM to find out how much current an LED draws
To find out how much current a buzzer takes, just use the same circuit and DMM setting, except with the buzzer in place of the LED.
Finding out how much current a motor uses
WARNING:
**TO AVOID DAMAGING THE METER, **USE THE 10 A. JACK AND THE 10 A. SETTING, WHEN MEASURING THE CURRENT TO A MOTOR. ****
