I took a guess on this one

4. In the circuit below find E, the erf of the battery in the center branch (in volts). The current in the 5.00 02 resistor is 8.00 A in the direction shown by the arrow The direction of the current in the 2.00 Q resistor is also shown by an arrow but its value is not given. (A) 17.5 (B) 20.0 [C) 32.5 SA (D) 25.0 (E) 14.0 (F) 11.2 60V E 5.12 212 1052 W
