EE 213: Extra Credit 1 10 points due Tuesday, October 7 th + - R A R B R C R 1 R 1 R 2 R 2 V dc x y No Exceptions Consider a common household toaster. A simplified circuit model for one side of the heating element of the toaster is given. It consists of a resistor network and a dc voltage source. In this exercise, you will design the toaster resistor network based on power dissipation requirements. The information given includes: The dc voltage source is assumed to be the average value of a stepped-down standard residential supply of 15 V. The power dissipation per unit length (i.e. heat generation) for each resistor is 120 W/ft. The resistors that heat the length (x) must dissipate

Unformatted text preview: the same amount of heat. The same is true for the resistors that heat the height (y). • For this toaster, the heating elements are designed such that x = 4 inches and y = 2 inches. • The power dissipated per unit length by R 1 is the same as the power dissipated per unit length by R A . Design the resistors and determine the current and power dissipated by each one. You must show all your work to receive any credit. Insufficient work will receive zero points. Writing a matlab or mathcad program would be useful, but is not required for a solution....
