# Shunt taps (video)

Where do you tap a 0.5 mΩ shunt?

0:19, with sound. [Read Note 5](https://nearfieldnotes.com/notes/shunt-taps/) for the full answer, with figures, conditions and sources.

## Transcript

Does it matter where you tap a current shunt?

2 mm out, 10 A reads as 14.1.

From the middle of the inner edges, it reads right.

Each voltage line the taps cross adds 5%.

A 4-terminal shunt reads right on every board I simulated.
