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?
