1. Transformers and Its Applications
Transformers as the name implies transforms electrical energy by changing the voltage from high to low.
It permits electricity to be send out high voltages at long distances, and utilized at lower voltage. Voltage
detects how strong or how many currents are carried out over short or long distances.
Transformers are utilized mainly to alter the number of amperes, volts, watts and electrical current from
the power source directly to where they are needed. It changes the voltage input to a specific value of
voltage output. It can either function to step up (increase) the voltage, or step down (decrease) the
voltage.
There are many uses for transformers. However, in some electronic machines, it is embedded so you
cannot actually see it. It is present in computers that covert for instance the incoming 120 volts into 5 and
12 volts respectively. It can also be found in adapters for electronics.
Commonly seen in mobile chargers where it lowers the incoming 120 volts into lesser voltage so that
mobile can receive it without any electrical faults. Electric Transformers performs by supplying the
correct electric current from one transformer to another through the use of circuit. It comes in range of
low voltage, high voltage and step down.
AC Power Transformers are used to change Alternating current voltage in AC power circuits. This is why
AC is more advantageous than DC (direct current). It is a dual electromagnet which is consists of two sets
of wires for input and output voltages. It is used to lower currents so electronic and electrical supplies can
be used safely at home.
Step down Voltage Transformer is made to lower electrical voltage. It has primary voltage which is
higher than the secondary voltage. This is why it is called “step down” as it lowers the current. It is used
in order to utilize 110v product in a country with a 220v supply. It alters electrical voltage from one level
to a lower level. It is used in applications such as power distribution, electrical isolation, control and
instrumentation.
Step up Voltage Transformer has secondary voltage which is higher than its primary voltage. It
generally "steps up" the voltage applied to it. For instance, it is required in order to use an appliance with
220v in a country with 110v supply. It is widely used in power transmission system where there is a need
to convert the power from generator or power source to a very high current.
