+//Chapter 5_Monolithic Components
+//Capation : Resistance and Sheet resistance
+//Example5.3: a)A base diffusion layer length is 100um and it's width is 10um.The sheet resistance of the layer is 100 ohm/square.Calculate its resistance.
+//b) Calculate the sheet resistance of a 20um thick,5 ohm-cm ep-layer.
+//a)Solution: 
+L=100;//base diffusion layer in um
+W=10;//base diffusion width in um
+Rs=100;//sheet resistance in ohm/square
+R=L*Rs/W;
+disp('resistance of base diffusion layer is:')
+disp('Ohm',R)
+//b)Solution:
+Pe=5*10^-2;//ep-layer resistivity in ucm
+t=20*10^-6;//thickness of the layer in um
+Rse=Pe/t;//sheet resitivity of ep-layer
+disp('sheet resistance of ep-layer is:')
+disp('Ohm',Rse)
