Combination of Resistors: Practice Problem & Solution

Identify the set in which all the three materials are good conductors of electricity (1994)
Cu, Hg and NaCl
Cu, Ge and Hg
Cu, Ag and Au
Cu, Si and diamond

Solution Explained:

To solve this problem, we apply the core principles of Combination of Resistors. Understanding the underlying formula is key to arriving at the correct answer below:

Copper (Cu), Silver (Ag), and Gold (Au) are transition metals. They have an abundance of free electrons available for conduction, making them all excellent conductors of electricity.
