Helpo please help help I have no time quick I’m in the exam

Explanation:

calculate effective resistance of the resistors

= 80 + 120

= 200

overall resistance = 48 ohms

so overall current flowing through circuit

I = V / R

I = 12 / 200

I = 0.06 A

since circuit is in series, current is same at every point so...

potential difference across 80 = R x I

= 80 x 0.06

answer is potential difference = 4.8 V

hope this helps

please mark it brainliest

I just learned this chapter recently

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
