Battery Load Current

Project Number: 32

Description: Move the meter (M6) to the new location shown and set it to the 50mA setting. Set the slide switch (S5) to position B and see how high the current is when the battery is running all these devices. You may see that the current is very high, which explains the battery voltage dropped in the preceding project. Do you know which devices need most of the current? Remove some and see how the current changes to see if you were right.

Snappy: Your M6 meter is a simple meter, don't expect it to be as accurate as normal electronic test instruments.
