Capacitance From a Voltage vs. Time Graph

%% Capacitance From a Voltage vs. Time Graph
% Calculates capacitance by using a voltage. vs time graph.
% Notes and clarifications are at the bottom of the code

% Inputs and Variables
V0 = input('What is the voltage of the battery?\n');
R = input('What is the resistance in ohms?\n');
disp('These next inputs require a (V,t) coordinate pair from the curve')
t = input('What is the value of t at the intersection?\n');
V = input('What is the value of V at the intersection?\n');

% Outputs and Equations
C = t/(R*log(V0/(V0-V)))
fprintf('The capacitance is %.4e F', C);

%{
V and t are found by using the graph and seeing where the the curve passes
    through an intersection point. V is the y-coordinate and t is the
    x-coordinate
The output is rounded to 4 places after the decimal point. To change or remove
    this feature, edit the .# in the fprintf line
