Question1

The 300V output of a transformer secondary winding is fed in to a 35Ω load-

find the important information, put it in a key and find the missing information before answering the question

Voltage- 300V

Resistance- 35Ω

Current= 8.6A voltage = I x R

300/35= 8.6 Current = V/R

Resistance = V/I

Now we know the current we can go on to answer the questions:

a) calculate the power in the load

b) if the primary Voltage is 400V calculate the primary current

c) The secondary is wound with 340 turns, how many turns are there on the primary.

d) The primary voltage falls to 391 volts. How many turns need to be added to the secondary to maintain an output of 300V
