Question

A step up transformer has turns ratio 10: 1. A source of emf 2 volts is fed to the primary. Secondary voltage developed is (A) 20 V (B) 10 V (C) 2 V (D) zero

Tardigrade Admin · Accepted Answer

Given,NS: NP = 10: 1 , VP = 2V ∴ VS = (NS/NP) VP = (10/1) × 2 = 20 V

Q. A step up transformer has turns ratio $10 : 1$ . A source of emf 2 volts is fed to the primary. Secondary voltage developed is

20 V

10 V

2 V

zero

Given, $N_{S} : N_{P} = 10 : 1, V_{P} = 2 V$
$∴ V_{S} = \frac{N _{S}}{N _{P}} V_{P} = \frac{10}{1} \times 2 = 20 V$
