During the experiment, you adjusted the length of the rheostat LL6 so that 1 glow flowed through bulb H. Now that we have seen that the (conduction) current measured by a DMM corresponds to the same physical concept as ‘glow’, it makes sense to ask "what current goes through bulb H when 1 glow goes through bulb H?" The consensus in the past has been about 30 mA but you might have been using a slightly larger or smaller current. Remember that you assumed that the bulbs in circuit 7 were identical. If the resistance of rheostat LL6 has been adjusted so that 30 mA flows through bulb H then what current flows through bulb B? What current flows through bulb C?

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.
