The RC circuit shown below has a variable resistance R (t) given by the following expression:
\(R\left( t \right) =R_0 \left ( {1-\frac{t}{T}} \right)for\;0 \le t < T\)
Where R0 = 1Ω, and C = 1 F. We are also given that T = 3 R0C and the source voltage is Vs = 1 V. If the current at time t = 0 is 1 A, then the current I (t), in amperes, at time t = T/2 is _______ (rounded off to 2 decimal places).
