In the following circuit, the current through the resistor `R (=2Omega)` is I amperes. The value of I is

Answer

A

Explanation

The equivalent resistance of balanced wheatstone
bridge is
`R_(eq) = (3 xx 6)/(3+6) = 2Omega`

The equivalent resistance of balanced wheatstone
bridge is
`R_(eq) = (6 xx 18)/24 = 9/2 Omega`
`:. I = 6.5/(2+4.5) = 1A`
