RTD (Resistance Temperature Detector)

A resistance temperature detector is a passive electronic device or a sensor. The name itself suggests that it is related to resistance, temperature, and detection. Similarly, its resistance changes when there is a temperature change; the resistance increases when the temperature of the RTD device increases or vice-versa. It is also known as a resistance thermometer. Its working is similar to the thermocouple.

Each terminal of a small polarity-independent incandescent bulb is connected to the positive terminals of two (2) DC voltage sources. The negative terminals of these sources are connected together. The first voltage source can have a range of value from 0-12, incrementable by 1.5 volts every turn of the rotary switch (i.e. 0 V, 1.5 V, 3 V, 4.5 V .... 12 V). The voltage of the second source is unknown. Using a luxmeter, the brightness of the lamp was measured for every increment of voltage of the first source. The following observations were recorded: a. 1.5 V produces a higher brightness than 3 V b. 0 V produces a higher brightness than 1.5 V c. 12 V produces higher brightness than 9 V d. 12 V produces equal brightness as 3 V What is the voltage of the second source?
