[searley]

a transformer has a ratio of 12:2 if the primary voltage is 200v.the secondry voltage will be ?

 

[Tazmanracer]

33.333v

Would be same as ratio of 6:1

Divide 200 by 6 to get secondary voltage

As Tazman says 33.333..

But it is worth remembering basic transformer formula rules..

(Vp/Vs) = (Np/Ns) = (Is/Ip)

where;

Vp is Volts primary

Vs is Volts secondary

Np is No of turns primary

Ns is No of turns secondary

Ip is Current primary

Is is Current secondary

so with your question

(200/Vs) = (12/2)

200/Vs = 6

200/6 = Vs

Vs = 33.3333v
