The response of an electrical circuit can be describe by V = BERC Please notice that this is very similar to the equation y=Ae^-x We will call this the simple form Let y=V A=B e = Eulers number = 2.7183 -x=-t/RC In the last substitution, "R" and "C" are constant, and "t" is the variable of time. Now, re-arrange the 'simple' form, solving for A A=y/ex Next, substitute the values as required, they are shown above. Use the equation editor to show the equation for B. Once you create the text box to display the equation, solve for ß using Excel See the example if you need some help on the calculation for e^-x Calculate ß if V = 10 V, R = 220 , C = 0.0056 F, and t = 0.25 s. Remember to use cell references and arithmetic operators in the reference cell
