(True or False) The cables used to transfer electric energy from the generating station to the consumers must be of low resistance to reduce losses due to joule heating

That is true. However, raising the voltage of the transmission lines helps a great deal to reduce joule heating losses, by reducing the I^2 factor in I^2*R.

True. The cables used to transfer electric energy from the generating station to the consumers must indeed have low resistance to reduce losses due to joule heating. When electric current flows through a conductor, such as a cable, heat is generated due to the resistance of the conductor. This is known as joule heating.

To transfer electric energy over long distances, high-voltage transmission lines are used. These high-voltage transmission lines are typically made of materials with low resistance, such as copper or aluminum. The low resistance of the cables helps to minimize the amount of heat generated and, consequently, reduce energy losses.

By reducing energy losses, the efficiency of the power transmission system increases. This means that more of the generated electric energy reaches the consumers, resulting in less wasted energy and a more environmentally friendly and cost-effective system.

In summary, using cables with low resistance helps to minimize energy losses due to joule heating and improve the overall efficiency of the power transmission system.
