Use the formula for charging:
5 Time constant(T) = 10, therefore Time constant(T) = 2.
%Equilibrium = (1 - e^(-t/T)),
0.5 = (1 - e^(-t/2)).
And we get; t = 1.386 s.
5 Time constant(T) = 10, therefore Time constant(T) = 2.
%Equilibrium = (1 - e^(-t/T)),
0.5 = (1 - e^(-t/2)).
And we get; t = 1.386 s.
