Question

in a step-up transformer the turn ratio is 1:2 A lenchlanche shell (e.m.f. 1.5v) has been connected across the primary the voltage across the secondary is what​

Answer 1

Answer:

Leclanche cell works on direct current and thus gives out direct current. The ratio given here won't work since the transformers work on alternating current not on direct current. Thus the voltage developed in the secondary would be 0V.
