If there are 3 resistors of. 5 ohms, 1 ohms, and 1 ohms connected in parallel then what is the equivalent resistance

Answer:0.45ohms

Explanation:

Let R be there equivalent resistance

1/R=1/r+1/r+1/r

1/R=1/5+1/1+1/1

1/R=1/5+2

1/R = (1+10) / 5

1/R=11/5

Cross multiplying we get

11R=5

Divide both sides by 11

11R ➗ 11=5 ➗ 11

R=0.45ohms
