Acombined circuit has two resistors in parallel (34.0 ohms and 41.0 ohms) and another in series (15.0 ohms). if the power source is 9.0 volts, what will the current be? . a.. 0.054 amps. b.. 33.6 amps. c.. 0.27 amps. d.. 0.48 amps. e.. 0.60 amps.

If the power source is 9.0 volts, the current will be 0.27 amps. The correct answer between all the choices given is the third choice or letter C. I am hoping that this answer has satisfied your query and it will be able to help you, and if you would like, feel free to ask another question.

Answer : Current, I = 0.27 amps

Explanation :

Given that,

Two resistors R₁ = 34.0 ohms and R₂ = 41.0 ohms in parallel and another resistor R₃ = 15.0 ohms in series.

The voltage across them is 9 volts.

Taking the equivalent of R₁ and R₂ :

Now, Taking series combination of and R₃

So,

Using Ohm/s law :

I = 0.268 A

or

I = 0.27 amps

So, the correct option is (C) " 0.27 amps "

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
