Extracted text: During the measurement of a low resistance using a potentiometer, the following readings were obtained: Voltage drop across unknown resistance = 0.531 %3D Volts. Voltage drop across a 0.1 Ohm standard resistance connected in series with the unknown resistance = 1.083 Volt. %3D Value of the unknown resistor is (a) 49.03 milliohm (b) 108.3 milliohm (c) 20.4 milliohm (d) 53.1 milliohm
