Question 22
Boojho made the circuit shown in the figure. He wanted to observe what happens when an electric current is passed through water. But he forgot to add a few drops of lemon juice to water. Will it make any difference to his observations? Explain.

Answer 1

No, current will pass through the circuit, if the water is distilled water and lemon juice is not added. If the water is salty, a small current will pass through the circuit. Adding few drops of lemon juice in water will increase the conductivity of the solution and a large amount of current will flow easily.
