I'm confused with this one, here's what i got

Question

45.0 v/ 40.0Ω = 1.125 A
is the answer b?

A 10.0 Ω resistor is in parallel with a 30.0 Ω resistor and supplied by a 45.0 V battery. What is the total current drawn from the battery?

0.003 A

1.10 A

6.00 A

338 A

Answer 1

NO!!!

Answer 2

10 in PARALLEL with 30
1/R = 1/R1 + 1/R2
or
R = R1 R2 /(R1+R2)

Answer 3

R = 10*30 / (40)
= 7.5

45/7.5 = 6 Amps

Answer 4

okay, thx, i take online school and it's much harder for me
