Question

In step-down transformer, the AC output gives the

(a) current more than the input current

(b) current less than the input current 

(c) current equal to the input current

(d) voltage more than the input voltage

Answer 1

(a) current more than the input current

There is no loss of power in an ideal transformer.

⇒ V_sI_s = V_pI_S

In a step down transformer, V_s < V_p

⇒ I_s > I_p
