In an energy efficiency project for a house, a circuit with three resistors in parallel was developed to control the brightness of the lights. The first resistor has a resistance of 2Ω, the second one of 4Ω, and the third one of 8Ω. (a) Calculate the total resistance of the parallel circuit. (b) If the circuit is connected to a 12V power supply, what will be the total current in the circuit? (c) Determine the current in each resistor of the circuit.Answer sheet:

Beverages can be chilled more quickly using styrofoam boxes containing ice and a little commercial coarse salt. In this process, the ice melts with consequent formation of liquid and cooling of the beverages. An erroneous interpretation, based on common sense, relates this effect to the great ability of coarse salt to remove heat from the ice. From a scientific point of view, rapid cooling occurs due to more efficient heat transfer between the ice, salt, and beverages.

A motor operates according to the Carnot cycle between two thermal sources. The hot source is at a temperature of 500 K and the cold source at 300 K. Determine the efficiency of the motor, knowing that the efficiency of the Carnot cycle is calculated by the expression 1 - (Tcold/Thot), where Tcold and Thot are the temperatures of the cold and hot sources, respectively. Discuss briefly the importance of the maximum efficiency of the Carnot cycle in practical applications of thermal engines.
