Current in RL Circuit

%% Current in RL Circuit
% Determines the maximum current in the circuit and the current at a
% specific time

% Inputs and Variables
R = input('What is the resistance in the circuit?\n');
L = input('What is the value of inductance?\n ');
V = input('What is the voltage?\n');
t = input('What is the specific time?\n');

% Outputs and Equations
Imax = V/R;
Tau = L/R;
I = V*(1-exp(-t/Tau))/R;
fprintf('The maximum current is %.4e A and the specific current is %.4e A \n', Imax, I)
