The circuit shown in the figure has reached steady state with thyristor ' $\text{T}$ ' in $\mathrm{OFF}$ condition. Assume that the latching and holding currents of the thyristor are zero. The thyristor is turned $\mathrm{ON}$ at $t=0 \mathrm{~sec}$. The duration in microseconds for which the thyristor would conduct, before it turns off, is ________(Round off to $2$ decimal places).
