Answer:

Secondary current is  8A

Explanation:

Data :

Primary supply = Vp = 240 V

Secondary supply = Vs = 60V

Primary current = Ip = 2A

Secondary current = Is = ?

Formula  :     Vp × Ip = Vs × Is

So for secondary current formula becomes

          Is = (Vp/Vs)×Ip =  (240/60) × 2

     Is = 4 × 2 = 8A
