Explanation / Answer

Answer:-

Answer -

Vp = 120 V

Np = 310

Ns = 1390

Is = 17 A

for transformer we know a equation

Secondary voltage (Vs) / Primary Voltage (Vp) = Secondary Turns (Ns) /Primary Turns (Np) = Secondary Current (Is ) / Primary Current (Ip)

Vs/ Vp = Ns / Np = Is /Ip

Part-1 ) What is the output voltage (Vs)

Vs = Vp ( Ns /Np)

Vs = 120 ( 1390/ 310)

So Vs = 538 V.

Part-b ) What is the Primary current.?

use below equation

Ns / Np = Is /Ip

rewrite for Ip =?

Ip = Is* ( Np /Ns)

Ip = 17 ( 310 / 1390)

Ip = 3.79 A.

So the primary current is 3.79 A.
