What is the total resistance of the circuit? (must include unit - ohms)

Answer:4 ohms
Explanation:
R1=24 ohms
R2=8 ohms
R3=12 ohms
Let total resistance Be R
It is a parallel connection
1/R=1/R1 + 1/R2 + 1/R3
1/R=1/24 + 1/8 + 1/12
1/R=(1+3+2)/24
1/R=6/24
Cross multiply
6R=24
Divide both sides by 6
6R/6=24/6
R=4
Total resistance =4 ohms
