Question

You are given three resistance each of 3 Oham how can you arrange them if value of effective resistance is 4.5 O ham

Answer 1

Answer:

Arrange two resistor in parallel and third one in series with other two which are parallel .

Explanation:

You will get following

1/R = 1/3+1/3

R=1.5 ohm

Third is in parallel

1.5+3= 4.5 ohm
