Explanation / Answer

here,

Np = 280 turns

a)

Vs1 = 6.25 V

Vp = 240 V

Ns1/Np = Vs1/Vp

Ns1 = 280* 6.25 /240

Ns1 = 7.3 turns

b)

Vs2 = 13.5 V

Vp = 240 V

Ns2/Np = Vs2/Vp

Ns2 = 280* 13.5 /240

Ns2 = 15.75 turns

c)

Vs3 = 475 V

Vp = 240 V

Ns3/Np = Vs3/Vp

Ns3 = 280* 475 /240

Ns3 = 554.17 turns

d)

Vs1 = 6.25 V

the maximum output current be Is1

Ip * Vp = Is1 * Vs1

5 * 240 = Is1 * 6.25

Is1 = 192 A
