Question
1)
The sinusoidal voltage output from the AC generator oscillates between 500 V and -500 V. The circuit for an ideal transformer is constructed with a generator, transformer and a 30 ? resistor . The generator makes 4 loops with the transformer and the resistor makes 8 loops with the transformer (the figure does not show these loops accurately). What is the maximum voltage across the resistor R ?
V= V
2)What is the average power dissipated in R?
P = W

The generator makes 4 loops with the transformer and the resistor makes 8 loops with the transformer (the figure does not show these loops accurately). What is the maximum voltage across the resistor R ? What is the average power dissipated in R?Explanation / Answer
a)
V1/V2 =N1/N2
500/V2 =(4/8)
V2 =1000 V
V=V2=1000 V
b)
Vrms =V/sqrt(2) =707.1 V
Pav=Vrms^2/R =707.1^2/30
Pav =16,666.67W
