Answer: 4 ohms

Explanation:

For parallel connection we use this formula

R=equivalent resistance

R1=24 ohms

R2=8 ohms

R3=12 ohms

1/R=1/R1 + 1/R2 + 1/R3

1/R=1/24 + 1/8 + 1/12

1/R=(1x1+3x1+2x1) ➗ 24

Cross multiplying we get

24x1=(1x1+3x1+2x1) x R

24=(1+3+2) x R

24=6xR

Divide both sides by 6

24 ➗ 6=6xR ➗ 6

4=R

R=4 ohms
