Dear student,

In this case, both the bulbs will glow but their brightness may be different depending upon the bulbs’ ratings. If the bulbs have resistancesR_1,R_2, the current in the circuit will bei=\dfrac{V_1+V_2}{R_1+R_2}.

Hence the voltages across the two bulbs will beiR_1,iR_2, respectively.
