Atransformer connected to a 120--v ac line is to supply 12.0v (rms) to a portable electronic device. the load resistance in the secondary is 4.70 ohms
1) what should the ratio of primary to secondary turns of the transformer be?
n1/n2 =
2) what rms current must the secondary supply?
i = a
3) what average power is delivered to the load?
p = w
4) what resistance connected directly across the source line (which has a voltage of 120? v ) would draw the same power as the transformer?
r = ohms
