# You Have Three Resistors of Values 2ω, 3ω and 5ω. How Will You Join Them So that the Total Resistance is Less than 1ω? Draw Diagram and Find the Total Resistance. - Physics

You have three resistors of values 2Ω, 3Ω and 5Ω. How will you join them so that the total  resistance is less than 1Ω? Draw diagram and find the total resistance.

#### Solution

The three resistors should be connected in parallel
To get a total resistance less than 1Ω

Let ' R be the total resistance.
Then,

1/R =1/2+1/3+1/5=(15+10+16)/30=31/30

Or, R =30/31=0.97Ω
