An aerospace technician measures the total resistance of a redundant array of identical micro-resistors connected in parallel within a satellite's telemetry circuit. The technician repeats the measurement of the equivalent resistance three times using a high-resolution multimeter.

The table below displays the recorded values when 4 micro-resistors are connected in parallel:

Number of resistorsReading 1 (Ω\OmegaΩ)Reading 2 (Ω\OmegaΩ)Reading 3 (Ω\OmegaΩ)Mean (Ω\OmegaΩ)
