This question really has me stumped and I don't know why, I seem to have forgotten the process . . .

A model electric train requires 6 V to operate. If the primary coil of its transformer has 240 windings, how many windings should the secondary have if the primary is connected to a 120 V household circuit?

2. Is this it?

6/120 = N/240 (240) 6/120 = n/240 (240)

12 = N
