Can an efficient transformer step up energy? Defend your

Step 1 of 3

An efficient transformer can step up energy, but it depends on the specific design and operating conditions of the transformer. In general, a transformer works by using electromagnetic induction to transfer energy from one circuit to another through a shared magnetic field. The primary winding of the transformer is connected to the source of electrical energy, and the secondary winding is connected to the load. By changing the ratio of the number of turns on the primary winding to the number of turns on the secondary winding, the transformer can step up or step down the voltage.
