Question

A student, while making a circuit to make a bulb glow using a dry cell, conected the plastic covering of the wire to the cell, instead of the metal wire inside it. Will current flow in the circuit? Why?

Answer 1

No, the current will not flow in the circuit. For the current to flow in the circuit, the metal wires should be connected to the cell and not the plastic covering. Plastic is an insulator which obstructs the current flow. Therefore, it should be ensured that only the metal portions of wires are connected to the cell because metals are good conductors, which allow the easy flow of current in the circuit.
