Question

how do you detect whether the liquids conduct electricity of not/how will you detect the weak currents through liquids?​

Answer 1

Liquids can be tested to check if they are good conductors of electricity. The free ends of a tester is dipped into liquid to be tested for the glowing of bulb. If the bulb glows, then it is good conductor and if the bulb does not glow, it is a poor conductor. All liquids are not good conductors of electricity.

Answer 2

Answer:

If a weak electric current flows through the liquid in the circuit the magnetic needle of compass will show deflection. ... If a compass surrounded by wound of electric wire of a circuit including a liquid in it shows deflection, it will mean that the liquid conduct electricity.
