The RC circuit shown below has a variable resistance R(t) given by the following expression: R(t)=R0(1-t/T) for 0≤t0=1 Ω 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).
Correct : 0.25
