Question

A step up transformer has turn ratio 10: 1. A cell of emf 2 V is fed to the primary, then the secondary voltage developed is (A) 20 V (B) 10 V (C) 2 V (D) Zero

Tardigrade Admin · Accepted Answer

A transformer is essentially an AC device, it does not work on DC. So, voltage developed across secondary is zero.

Q. A step up transformer has turn ratio $10 : 1$ . A cell of emf $2 V$ is fed to the primary, then the secondary voltage developed is

20 V

10 V

2 V

Zero

A transformer is essentially an $A C$ device, it does not work on $D C$ . So, voltage developed across secondary is zero.
