That is, if the secondary coil has a greater number of turns than the
primary (Ns > Np), the voltage is stepped up (Vs > Vp) This type of
arrangement is called a step-up transformer However, in this arrangement,
there is less current in the secondary than in the primary (Np/Ns < 1 and Is
< Ip) For example, if the primary coil of a transformer has 100 turns and
the secondary has 200 turns,  Ns/Np = 2 and Np/Ns=1/2
