Question

please answer my question quick. I need it immediately​

Answer 1

Explanation:

hope this answers the question

the final resistance is 24 ohm and potn diff is 5V across lamp

Answer 2

Hi friend here is your answer.

R

$We \: \: knew \: \: the \: \: \\ formula \: \: for \: \: finding \: \: series \: \: resistance \: \: \\ </h3><h3>R _{s} =R1 + R2 \\ R _{s} = 20ohm + 4ohm \\ R _{s} = 24ohm$

Hope my answer will help you.

Potential difference between lamp is 5voltage.
