(engineering application – electric circuits) The combined resistance RT of three resistors R1, R2, and R3 in parallel is given by Write a script where you create variables for the three resistors and store values in each (i. e. make them up), and then calculate the combined resistance. Document every part of the script.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
