in a step-up transformer, the turn ratio is `1:2` leclanche cell (e.m.f. 1.5V) is connected across the primary. The voltage devloped in the secondary would be

A

3 V

B

`1.5 V`

C

`0.75 V`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
A
`(V_(s))/(V_(p))=(N_(s))/(N_(p))=(V_(s))/(1.5)=(2)/(1)=V_(s)=3 V`
