Question

Choose the INCORRECT relation among the following:

• A. $\text{Ampere}=\frac{\text{Coulomb}}{\text{Second}}$
• B. $\text{Volt}=\frac{\text{Coulomb}}{\text{Joule}}$
• C. $\text{Ohm}=\frac{\text{Volt}}{\text{Ampere}}$
• D. $1\text{Coulomb}=6.25\times {10}^{18}$$\text{electron charge}$

Answer 1

The correct option is B $\text{Volt}=\frac{\text{Coulomb}}{\text{Joule}}$

We know that
Potential (or, potential difference)}= $\frac{Work}{Charge}$
So, Volt = $\frac{Joule}{Coulomb}$

Thus, Option B is incorrect.
