Question

One 10.0 Ω resistor is wired in series with 10.0 Ω resistors in parallel. A 45.0 V battery supplies power to the circuit. What is the total current through the circuit?

A. 3.0 A

B. 1.5 A

C. 0.75 A

D. 0.33 A

Answer 1

Do you mean

one 10Ω is in series with two 10Ω in parallel?
the ones in parallel are worth 5Ω so the total equivalent resistance is 10+5=15.
Use V=IR

Answer 2

thx, i did not know that, so the answer is D :)

Answer 3

V/R = i = 45/15 = 3 amps

Answer 4

ohh oops, i did 15/45, thank you, Damon

Answer 5

You are welcome.
