3. If you have three 15 ohm resistors wired in parallel, what will the
equivalent (total) resistance be?
a. 45 ohms
b. 3.33 ohms
c. 14.6 ohms
d. 5 ohms
Other:

Answer 1

d. 5 ohms

Step-by-step explanation:

For resistors in parallel, the equivalent resistance is found with:

1/Req = ∑(1/R)

1/R = 1/15 + 1/15 + 1/15

1/R = 3/15

R = 15/3

R = 5
