Determine the equivalent resistance of networks shown in figure.

Options

A. `2 Omega `
B. `3 Omega`
C. `6 Omega`
D. `12 Omega`

Answer

A

Explanation

`2 Omega `
Resistance for A-F-E 6`Omega , R_(AE) = 3 Omega `
Resistance for A-E-D ` 6 Omega , R_(AD) = 3 Omega `
Resistance for R-D-C` 6 Omega , R_(AC) = 3 Omega`
Resistance for R-C-B `6 Omega`,
So, `(1)/(R_(AB)) = (1)/(6) + (1)/(3) = (1+ 2)/(3) = (1)/(2) " " therefore R_(AB) = 2 Omega`
