USES OF TRANSFORMER
 
  1. A transformer is used in almost all a.c. operations:
  2. In voltage regulator for T.V.,refrigerator, computer, air conditioner,etc.
  3. A step down transformer is used for welding purposes.
  4. A step down transformer is used for obtaining large current.
  5. A step up transformer is used for the production of X-Rays and NEON advertisement.
  6. Transformers are used in voltage regulators and stabilized power supplies.
  7. Transformers are used in the transmissions of a.c. over long distances.
  8. Small transformers are used in Radio sets, telephones, loud speakers and electric bells etc.


CONCLUSION
 
  1. The output voltage of the transformer across the secondary coil depends upon the ratio (Ns/Np) with respect to the input voltage
  2. The output voltage of the transformer across the secondary coil depends upon the ratio (Ns/Np) with respect to the input voltage
  3. There is a loss of power between input and output coil of a transformer.


PRECAUTIONS
 
  1. Keep safe yourself from high voltage.
  2. While taking the readings of current and voltage the A.C should remain constant.
SOURCES OF ERROR
  1. Values of current can be changed due to heating effect.
  2. Eddy current can change the readings.
