# Two resistors are connected in parallel b/w A and B to give a net resistance of 2 ohms. When one of these resistors is broken, the net resistance becomes a 3 ohms. What is the resistance of the resistor that was broken?

the net resistance$R_{eq}=2 ohms$
when one of the resistance is broken the net resistance is only one of the resistance i.e.$R_{1}=3 ohms$.
$1/R_{eq}=1/R_{1}+1/R_{2}$.
so$R_{2}=6 ohms$.
