P.D across seconday coil / P.D across primarry coil =
Number of turns in the secondary / Number of turns in the primary.
Therfore,
N /240 = 6 /120
N = [6 /120]*240 = 12 turns.
Verified .

Obviously, the question can be answered. If the input data are crazy, then the answer will be equally crazy. More than 1 HP for a model train? I’d call that crazy…..
A model electric train requires 6 V to operate. When connected to a 120 V household circuit, a transformer is?
needed. If the primary coil of the transformer has 240 windings, show that there should be 12 turns in the secondary coil.
A model electric train requires 12 V to operate. If the primary coil of its transformer has 270 windings, how?
A model electric train requires 12 V to operate. If the primary coil of its transformer has 270 windings, how many windings should the secondary have if the primary is connected to a 120 V household circuit?
a model electric train makes one complete pass around a circular track every 15 seconds….?
a model electric train makes one complete pass around a circular track every 15 seconds. the train’s motor has a resistance of 6.0ohm and is connected to a 70.0V source. How much energy will the train use in 12 complete passes around the track?

I’m sure that if you’re looking for scale trains you can find them there.
Model railroading lasts a life time!

t = 15 sec/1 circle * 12 circles = 180 sec
P = E²/R = 70²/6 = 816.667 W
Energy = P*t = 816.667 * 180 = 147000 W∙sec = 40.833 W∙hr

is there anyone on the net interested in electric model Trains?
15 YRO located in Queensland, Australia wising to make friends.
Are there any American made model electric trains (new ones ) ?
