Suppose you have three resistor of `(20 omega),(50Omega)and (100 Omega)`.what minimum and maximum resistances can you obtain from these resistors?

Text Solution

Verified by Experts

Max. R = `(20+50+100) Omega`
= `170 Omega `
` min R =(1/ (5/100)+(2/200)+(1/100))`
` = (1/ (5+2+1/100)) `
` = 100/8 = 12.5 Omega ` .
