Explanation / Answer

A)
net resistance of the ckt, Rnet = 6.1/2 + 4.7/2

= 5.4 ohms

Current through the battery, I = V/Rnet

= 12/5.4

= 2.22 A

here Current is devied equally to the parallel combination.

so, I_6.1 = 2.22/2 = 1.11 A

I_4.7 = 2.22/2 = 1.11 A

B) Use Ohm's law, V = I*R

V_6.1 = 1.11*6.1 = 6.78 volts

V_4.7 = 1.11*4.7 = 5.22 volts
