An appliance transformer-converter is plugged into a 120 volt AC house outlet.
The primary coil has 200 windings of copper wire. The secondary coil
has 15 windings of wire.
Calculate the voltage output of the transformer-converter.
Vo/Vin=15/200

What???
To calculate the voltage output of the transformer-converter, we can use the transformer equation:
(V1 / V2) = (N1 / N2)
where:
V1 is the voltage in the primary coil (in this case, 120 volts AC),
V2 is the voltage in the secondary coil (what we want to find),
N1 is the number of windings in the primary coil (200 windings),
and N2 is the number of windings in the secondary coil (15 windings).
Let's substitute the given values into the equation and solve for V2:
(120 / V2) = (200 / 15)
To simplify this equation, we can cross-multiply:
120 * 15 = V2 * 200
1800 = V2 * 200
To isolate V2, divide both sides of the equation by 200:
1800 / 200 = V2
9 = V2
Therefore, the voltage output of the transformer-converter is 9 volts.
