Three resistors each of `4 Omega` are connected together to form a network. The equivalent resistance of the network cannot be

Options

A. `1.33 Omega`
B. `3.0 Omega`
C. `6.0 Omega`
D. `12.0 Omega`

Answer

B

Explanation

(b) If all are in series then `R_(eq) = 12 Omega`
If all are in parallel then `R_(eq) = (4)/(3) Omega = 1.33 Omega`
If two are in series then parallel with third,
`R_(eq) = (8)/(3) = 2.6 Omega`
If two are in parallel then series with third, `R_(eq) = 6 Omega`'
