Question

If all the resistors shown have the value 2 ohm each, the equivalent resistance over AB is

2 ohm
4 ohm
$1 \frac{2}{3} o h m$
$2 \frac{2}{3} o h m$

The correct answer is: $2 fraction numerator 2 over denominator 3 end fraction o h m$

$R subscript A B end subscript equals fraction numerator R over denominator 3 end fraction plus R$ = $fraction numerator 2 over denominator 3 end fraction plus 2 equals fraction numerator 8 over denominator 3 end fraction equals 2 fraction numerator 2 over denominator 3 end fraction capital omega$ .
