Q1:

In the given circuit, what is RUNK equal to if RV must be adjusted to 1,232 omega.gif in order to balance the bridge?

A 220 omega.gif

B 6,899 omega.gif

C 1,232 omega.gif

D More information is needed in order to find RUNK.

ANS:A - 220 omega.gif

In order to balance the bridge.

560/(560+100) = 1232/(1232+R).

So R = 220 ohm.
