Read the needle position on the mA scale. The middle galvanometer (the one whose needle points at +4 mA) is indicating a current of 4 mA.

Summary for the three gauges:
- Left: 0 mA (no current).
- Middle: +4 mA — 4 mA in the positive (marked) direction.
- Right: −5 mA — 5 mA in the opposite direction.
