Two IGBTs are connected in parallel as shown below with current sharing resistances. The total current $I_T=120A.$ The collector$-$emitter voltage drop of Q $1$ is $V_{CE1}=0\mathrm{.}9V$ and that of Q $2$ is $V_{CE2}=1\mathrm{.}1V.V_{CC}=50V,R_C=0\mathrm{.}4$

Design the resistors so that the total current is equally shared by the transistors.
