Question 3: A very simple model for the distribution of clectricity to a typical home is shown in the figure below. Some of components labeled a, b, c, d, c, f, g and h represent the electrical source to the home, some represent the wires that carry the electrical current from the source to the devices in the home requiring electrical power, some represent lamps, televisions, hair dryers and other devices that require power. Assume you are an engineer in charge of a project and one of your subordinate engineers reports that the interconnection in the figure does not pass the power check. The data for the interconnection are given in the table below. Is the subordinate correer? Explain your answer. If the subordinate is correct, find the error in the data. Explain your answer clearly. Based on your answer identify that which label(s) used for the electrical source, wires or other devices. a e h

A variable resistor enables one to change the resistance.  One design involves a horizontal tube of wire with a slider on the top.  By moving the slider, one can change the length of wire involved, thus changing the resistance.  Imagine a tube of wire with one layer made from wire 1.00 mm in diameter wrapped in a single layer with no gaps between the loops of wire ( the wire looks like a solid layer down the length of the tube).  The radius of the tube is 2.50 cm.  Moving the slider 1.00 cm changes the resistance of the variable resistor by 3.00 Ohms.  What is the resistivity of the wire, and what is it made of?

I need helpo with this. I need step by step solutions for this and I cant figure it out.  Wire to be used in buildings and homes in the United States is standardized according to the AWGsystem (American Wire Gauge). Wires are assigned a gauge number according to their diameter.The scale ranges from gauge 0000 to gauge 36 in 39 steps. The equation for the wire gauge interms of the wire diameter in millimeters is the picture. (a) What is the equation for the diameter in millimeters in terms of the wire gauge N?(b) You have two wires, one that has five times the diameter of the other. By how much do thewire gauges differ for the two wires? (Give your answer to the nearest integer.)
