Weak conductors of electricity

Question 1 How will you show that vinegar and lemon juice are weak conductors of electricity?

Question 2 How will you show that ordinary water or tap water is a weak conductor of electricity?

vinegar do not conduct electricity

When an ​electric current is passed through vinegar taken in a beaker ,then the bulb glows very dimly.

The very dim glowing of bulb indicates that though vinegar and lemon juice conduct electricity but they are weak conductors of electricity. If a large battery is not used to pass current through vinegar or lemon juice, then the bulbs may not glow at all.

If we take ordinary water in the beaker and pass electricity through it ,then the bulb will not grow at all even if a large battery is applied. This is because ordinary water or tap water is a weak conductor of electricity.
