A Wheatstone bridge is used to determine the value of unknown resistance \(X\) by adjusting the variable resistance \(Y\) as shown in the figure. For the most precise measurement of \(X\), the resistances \(P\) and \(Q\):
1. do not play any significant role.
2. should be approximately equal to \(2X\).
3. should be approximately equal and are small.
4. should be very large and unequal.
