MCQ
One Volt is equal to:
- A1 Joule
- B1 Newton/ Coulomb
- C1 Joule/ Coulomb
- D1 Coulomb/ Newton
✓
Answer
- 1 Joule/ Coulomb
Explanation:
The volt is a measure of electric potential. One volt is defined as the difference in electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. It is also equal to the potential difference between two parallel, infinite planes spaced 1 meter apart that create an electric field of 1 newton per coulomb. Additionally, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units (m, kg, s, and A)
$1\text{volte}=\frac{1\text{joule}}{\text{Coulomb}}$
