Transformer HELP!
A small transformer with 1200 turns In the primary coil is used to power a appliance that has a output voltage of 6V. The label o the transformer says that the input is 5W at 120V. What will be the output power of the transformer?
Given: V output= 0.6*10V (6V)
V output= 3.0*10^2 mA
Required: P Output
Analysis: P=IV
Solution: 3.0*10^2mA *0.6*10V
= 1.8*10^3W will it be the output power of the transformer?
B: Will the secondary coil have more, fewer or the same number of turns as the primary coil? Why?
It will have fewer turns.
