There are 10 ohm resistors in parallel. The equivalent resistance for two 10 ohm resistors in parallel is 5 ohm. The measured value, as shown in the picture, is 4.98 ohm (percent error of 4%).
The equivalent resistance for three 10 ohm resistors is 3.3 ohm. The measured value (see the photograph) is 3.5 ohm (percent error of 5%).
