A simple electronic resistance bridge is described. The bridge compares an unknown four-terminal resistor in the mOmega range with a precision resistance decade in the kOmega range. A lock-in amplifier is used as zero detector. With 10-mA exciting current a resolution better than one part in 3000 is obtained for unknown resistors in the range 3–100 mOmega. Experimental results are shown for a gold sample under pressure in the range 0–35° C and 0–1.3 GPa.
