Question

When two resistors of resistance r1 and r2 are connected in parallel, the net resistance is 3 ohm. When connected in series , its value is 16 ohm. Calculate the value of r1 and r2?

Answer 1

Answer:

i m sure it will help you just watch it carefully

Explanation:

Answer 2

Answer: For series combination

R¹+R²=16

R2=16-R1........1

For parallel combination

1/R1+1/R2=1/3

R1xR2/R1+R2=3

R1x16-R1/R1+16-R1=3

R1x16-R1/16
