Description : What are your thoughts about wireless electricity?
Last Answer : It’s a reality, but I think it will take time before it is commercialized.
Description : Copper wires are generally used for electrical power transmission instead of iron wire because (1) copper is cheaper than iron (2) copper is lighter than iron (3) copper is a better conductor of electricity than iron (4) copper can take higher power than iron
Last Answer : (3) copper is a better conductor of electricity than iron Explanation: Copper is generally preferred for electrical power transmission instead of iron because of its high electrical conductivity and low resistivity.
