1. A measuring device for measuring noise present in equipment having a prescribed resistance value, the measuring device comprising:
a first voltage-dividing circuit connectable to a direct-current power supply;
a second voltage-dividing circuit connected in parallel with the first voltage-dividing circuit;
a measuring unit that measures a first voltage-divided voltage output from the first voltage-dividing circuit and a second voltage-divided voltage output from the second voltage-dividing circuit;
a calculating unit that calculates a difference between the measured first voltage-divided voltage and second voltage-divided voltage; and
an output unit that outputs a calculated result,
wherein
the first voltage-dividing circuit is configured to output the first voltage-divided voltage from the equipment and a first resistor, the equipment and the first resistor being connected in series, and
the second voltage-dividing circuit is configured to output the second voltage-divided voltage from a second resistor having a same resistance value as a resistance value of the equipment, and a third resistor having a same resistance value as a resistance value of the first resistor, the second and third resistors being connected in series.
