Question

Which of the following statement(s) is correct while conducting electricity through vegetable oil?
A. The liquid (vegetable oil) allows the electric current to pass through. Since, it is a good conductor of electricity.
B. The circuit of the tester is complete but the bulb does not glow.
C. The circuit of the tester is not complete and hence the bulb does not glow.
D. Both A and B.

Answer 1

Hint: Conductor is a substance or material in which flow of current occurs from one direction to another. Oil is an insulator and is a bad conductor of electricity.

Complete step by step answer:
The oil by nature does not conduct electricity. It does not allow electric current to pass through. The circuit of the tester is not complete due to incapability of oil to flow the transfer of charge.
They are effectively used in transformers and switches due to insulating properties. The conductivity is dependent on several factors like base oil, water content, other additives and polarity.
The circuit of the substance should be continuous and without break. The circuit will only be complete if only there is no breakup of the substance. The flow of electrons will be affected by the completeness or incompleteness of the circuit.
The oil is low density compounds that have less number of ions or particles content in it which can conduct electricity. The vegetable oil is lighter than water and hence is low in polarity and density. So in vegetable oil the circuit of the tester is incomplete and the bulb does not glow

Hence option C is the correct .

Note:
Plastic, glass and wood are also bad conductors of electricity and are referred to as insulators. The electric field does not exist on the surface of an insulator.
