What are the SI units of the electric field?
AJoules per coulomb
BNewtons per meter
CNewtons per coulomb
DCoulombs per newton
Answer & Solution
Correct answer: C. Newtons per coulomb
1. The electric field is force divided by charge.
2. Force is measured in newtons and charge in coulombs, so the field is measured in newtons per coulomb.
3. Joules per coulomb is instead the unit of electric potential, and newtons per meter is a spring constant, so neither matches.
