Answer 1

110.4 v

Step-by-step explanation:

Find the equivalent resistance of the two parallel circuits

R1 and R2 in parallel = R1 * R2 / (R1+ R2) = 1 ohm

similarly R4 and R5 = 4.77 ohms

Now you can add the three resistances into one (R3=10)

1 ohm + 10 ohm + 4.77 ohm = 15.77 ohms

Now

V = IR

V = 7 amps * 15.77 ohm = 110.4 v
