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.
|Number turns `xx2`||`=`||Voltage `xx2`|
|Number turns `xx1/2`||`=`||Voltage `xx1/2`|
Or in terms of formula:
(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))
