Question
The primary coil of a transformer has 200 turns while the secondary coil has 1000 turns. What type of transformer is this? if the input voltage is 10V, what will be the output voltage?

Solution
The transformer is step-up transformer.
Given: Np = 200, Ns = 1000, Ep = 10, Es = ?
By relation
`"E"_"s"/"E"_"p" = "N"_"s"/"N"_"p"`
`"E"_"s"/10 = 1000/200`
or `"E"_"s" = (10 xx 1000)/200 xx 50` V
