Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.

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?
