1.	In a Wheatstone’s bridge experiment, a student by mistake, connects key (K) in place of galvanometer and galvanometer (G) in place of key (K). What will be the test for the balance of the bridge?
Answer» When the bridge is balanced, there will be no current in key, therefore a constant current will flow in the galvanometer. In balanced position, there will be a constant deflection in galvanometer and hence no change in its deflection on pressing the key.
