6.18 explain the use of step-up and step-down transformers in the large- scale generation and transmission of electrical energy

A transformer that is used to increase voltage is called step-up transformer. One that is used to decrease voltages is called step-down transformers. After generating electricity, electric currents are passed to a step-up transformer which increase the voltage and decrease the current. This is because higher currents need wide and expensive wire to pass through. Or else, energy is lost in form of heat. Using transformers mean we can have a solution to this problem. Before the electricity reaches home, those are passed through step-down transformers to decrease the voltage and increase the current at the same time.
