please answer the question below

the figure the resistances are R2 = 0.97 0 and R-u = 1.9 V), and the ideai batteries have ernfs E.I = 2.5 V, and Ea = E3 = 3.1 V. What. are the (a) size and {b) direction (up down) of the current in battery 1, the [c) size and (d) direction of the current in battery 2, and the (e) size and (f) direction ot the current in battery 3? (g) What is the potential difference - V.? Number Number Number Number Units Units Units Units
