Question

Verify that the units Weber and volt second are the same ?

Answer 1

Expand both sides in terms of base units and see if they are the same. 

From Faradays laws of induction induced emf = rate of change of flux linkage. Flux is measured in Webers, (=B x A)

The "Weber" is the SI unit for magnetic flux. In fundamental units, 

1 W = 1 kg m² / A s² 

The "Volt" is the SI unit for potential difference. In fundamental units, 

1 V = 1 kg m² / A s³ 

So, 1 W / s = 1 V.

Answer 2

same as the given answer.
