Transformers

EXPLAIN BEHIND THE PRINCIPLES OF TRANSFORMERS

Objectives:
a. Differentiate a step-up transformer from a step-down transformer
b. Identify appliances/equipment that require transformers
c. Relate the voltage and current in the primary and secondary coils to the numbers of turn in each.

Assignment: Research about these 3 objectives and post video and explanation on the blogs.

ANSWERS:

a. A STEP-UP TRANSFORMER is allows a device that requires a high voltage power supply to operate from a lower voltage source. The transformer takes in the low voltage at a high current and puts out the high voltage at a low current while the STEP-DOWN TRANSFORMER is allows a device that requires a low voltage power supply to operate from a higher voltage. The transformer takes in the high voltage at a low current and puts out a low voltage at a high current.
b. All the appliances which are functioning or dependent to electricity has a transformer or required a transformer.
c. Hence the step-up transformer has a great loop in secondary coil, so in step-down transformer has a less amount of loop in a secondary coil. So the induce voltage of the step-up transformer is greater than the other. So as a whole if the secondary coil loops is increases the greater the induce voltage and the primary coil reduces its induce voltage with same as vise versa.
