Answer:
Resistance to electrical currents
Explanation:
Conductors have low resistance to electrical currents, and are used to "conduct" the flow of electricity.
Insulators have very high resistance and are used to protect us from the flow of electricity.
A because of the resistors are four in this options first option is multiplied by 4
Linear expansivity, area expansivity and volume or cubic expansivity are
hydro: water pushing turbines to create electricity
wind: wind pushing wind turbines to create electricity
geothermal: heat from earth core creating steam which moves turbines and creates heat and electricity
