Are you new to the concept of transformers? If so, you may wish to learn a little about what a transformer is and how it works. A powerline can have anywhere from 20,000 to 765,000 volts of electricity. This amount of energy is great for distributing electricity across vast distances, but not so great for making the perfect piece of toast and powering many other household appliances. Therefore, the voltage coming from the community powerline needs to be stepped down to an acceptable 110 to 120 volts before it can be safely used in your home. This is done through the use of a “transformer.” Many will recognize this term, but fewer understand how a transformer actually works. A transformer is designed to transform one voltage into another. (A volt is simply the given energy, divided by its charge; or, the difference between the charges of two points.) You’ve most likely seen transformers atop utility poles in your neighbourhood, but their smaller counterparts can also be found in many household items, such as your cell phone charger.
So, how do transformers work? Every type of electrical circuit has a magnetic field that surrounds it. And, accordingly, modern physics states that magnetism and electricity are actually one in the same — electromagnetism. So, by altering the magnetic field, you are essentially changing the nature of electricity and altering its voltage in the process. In a step-down transformer, this can be done by changing the composition of a magnetic core such as ferrite or by reducing the voltage amount by moving reducing the number of windings in an electromagnetic coil.
In step-up transformers, you are simply lowering the current of electrons and allowing a higher voltage to pass through. This can be done by increasing the amount of turns (completed loops) in a shielded electromagnetic coil. While it may sound like you’re breaking the law of conservation of energy by stepping up the voltage, remember that you are not creating more energy than you are putting in, simply changing it into a different electromagnetic form.
