HINT: In a step-up transformer, the voltage is increased from primary to secondary or in other words we can say that voltage increases from more secondary winding turns than primary winding terms.
Complete step-by-step answer:
Or in a step-down transformer, we can convert the high voltage and low current from primary side of the transformer to low voltage and high current value on secondary side of transformer.
Step-up and step-down transformer:
1. The main difference between the step-up transformer and step-down transformer is that, in step-up transformers, there are a greater number of turns in the secondary coil, or in a step-down transformer, it can consist of a greater number of coils in the primary coil.
2. In step-up transformers, voltage is increased and current strength is decreased whereas in step-down transformers, voltage is decreased and the current strength is increased.
3. In step-up transformers, the wire of primary coil is thicker than that of secondary coil or in step-down transformer the wire of secondary coil is thicker than that of primary coil. In a step-up transformer it can extend the voltages from 220V-11KV or above, or in step-down transformers, it can reduce the voltage from 440-220V, 220-110V or 110-240V etc.
4. In a Step-up transformer it is generally used for power transmission. Generator Transformer in power plants is one example of Step-up Transformer, Or in Step-down Transformer is used in power distribution. Transformer in a residential colony is one example of a step-down transformer.
5. In step-up transformers, the number of turns in secondary coil is more than primary coil, or in step-down transformer, number of turns in secondary coil is less than primary coil.
NOTE: If input supply is given on a low voltage winding, then it becomes a step-up transformer. Both step-up and step-down transformers use electromagnetic induction to convert voltage between two circuits. We can use both types in the distribution of power supply stations to the end user.
