Hint: Lead wire is used in vehicles, control panels, e-ovens, electronic appliances, motors, generators, computers, printers, medical devices, and lots of electronic components. These components are generally very small.
Complete step by step solution:
Lead wires are generally used to make electrical connections in electronic devices. These electronic appliances are low voltage and low current. So the connection should be current sensitive. It is desired that the lead wires which are used in the connection should not contribute to the electrical effect of the individual electrical components.
If the resistance is small then even small variations of electric current will be responsive to the circuit because the appliances are low voltage. Hence, the resistance of the lead wire which is used as an electrical connection should be low.
The size of the electronic devices circuit is small. So, to connect them the size of the lead wire also should be small. The size of the lead wire is determined by the cross-section to be connected to the electronic device. So the diameter of the lead wire should be small.Hence, the lead wire should have smaller diameter and low resistance.
Therefore, the correct option is C.
Note: The lead wire is also used to check whether the electronic devices are working or not. To make the lead wire for this purpose the resistance should be small. Lead frames are used in the integrated circuit packaging by placing silicon chips on the lead frames.
