Question Electrical Engineering

Q 1. Use the program to obtain E at point A. Consider a disk of radius a = 1m and the discretization size d=0.1. Consider two different values of h: 1 cm, and 1 m. 2. Choose the value of rs to be 63 mC/m2.

3. Compare the obtained computational results with infinite surface charge approximation.

4. Derive an analytical expression of flux density E at point A. Show that:

5. Compare the computational results with the analytical solution. (Calculate the percentage error for each value of h).

6. Repeat part 5, using d=1 mm. Compare the computation time of part 5 and part 6.
