Question
Verify that the units weber and volt-second are the same.
✓
Answer
$\text{v}=\frac{\text{d}\phi}{\text{dt}}$
$\Rightarrow\text{d}\phi=\text{dt}$
Charge in flux has unit weber and potential difference as volt.
$\Rightarrow\text{d}\phi=\text{dt}$
Charge in flux has unit weber and potential difference as volt.
