Can you imagine life without electricity today? The answer is ‘No’. Electricity and Energy have become the most important parts of our everyday life. All our appliances work on electricity – TV, home theatre systems, refrigerators, microwave ovens, and most importantly – our mobiles are charged because of electricity! But, along with electricity comes voltage and fluctuation problems, because of which our appliances tend to malfunction. This is where transformers help us! They change the alternating current from one circuit to another by electromagnetic induction to reduce or increase the voltage of electrical equipment as required.
