Transformer – changing the number of turns

Scientists then changed the number of coils on the primary coil and secondary coil. They found that if you have twice as many turns on the secondary coil then twice the voltage will be present on the secondary coil.

Transformer with 4 primary coils and 8 secondary coils.

	Number turns `xx2`	`=`	Voltage `xx2`
and
	Number turns `xx1/2`	`=`	Voltage `xx1/2`

Or in terms of formula:

Voltage and turns relationship of transformers.

(NOTE: the two different coloured shades will help you remember voltage is one side and turns are the other (colours can be a great mnemonic))

or

`V_1/V_2=N_1/N_2`
