There are Electrical Transformers offered by us that are machines that transfer electricity from one circuit to another with changing voltage level but no frequency change. Today, they are designed to use AC supply, which means that fluctuation in supply voltage is impacted by the fluctuation in the current. An ideal transformer is a theoretical linear transformer that is lossless and perfectly coupled. Transformers are electrical devices with the capacity to change the voltage level of an alternating current (AC) in a circuit. Transformers are most commonly used for increasing low AC voltages at high current (a step-up transformer) or decreasing high AC voltages at low current (a step-down transformer) in electric power applications. The offered Electrical Transformers are very efficient.
