-What is the total resistance of the load?

-What is the magnitude of the circuit current?

-What is the current in one of the 10.0 Ohms resistors?

-what is the potential difference across 15.0 Ohms resistor?

1/10 + 1/10 = 2/10

so Req = 5 Ohms

add the 15 to get total R = 20 Ohms

i = V/R = 120/20 = 6 amps total

half of the current through each = 3 amps

V = i R = 6*15 = 90 Volts
