Explanation / Answer

Assuming the potential at the juntion betwwen R1, 5 ohm resistor and 3 ohm resistor to be 'x':

(x-4)/6 + x/6.5 + (x-10)/5.4 = 0 (Net current is zero, outgoing = incoming )

solve for x = 4.98 V approx

current in

energy delivered is potential difference * current passing through the battery

Energy delivered to each resistor is current2*resistance

Electrical energy is converted into heat enegy in the resistors.
Electrical energy is converted into chemical energy in the 4 V battery.
