Why should the free ends of a conduction tester not be connected for a long time?
Answers
Answer:
As metals are good conductors of electricity so they allow current to flow them easily. ... When the liquid does not allow the electric current to pass, the circuit of the tester is not complete and the bulb does not glow. 》》 The circuit is complete since free ends of the tester are dipped in a solution.

Explanation:
As metals are good conductors of electricity so they allow current to flow them easily. When the liquid does not allow the electric current to pass, the circuit of the tester is not complete and the bulb does not glow. The circuit is complete since free ends of the tester are dipped in a solution.
The deflection occurs because the circuit becomes complete since free ends of the tester are dipped in a solution. The solution is certainly a conducting solution. This is the reason why the compass needle shows a deflection.
