Question

4.1.2 quiz: electricity
question 9 of 10
which statement accurately describes current electricity?
a. negatively charged particles move from one point to another.
b. positively charged particles move from one point to another.
c. negatively charged particles build up on an objects surface.
d. positively charged particles build up on an objects surface.

Explanation:

Current electricity is the flow of electric charge. In most conductors (like metals), the charge carriers are electrons which are negatively - charged. Current electricity is about the movement of these charged particles (electrons) from one point to another. Option C and D describe static electricity (build - up of charge on a surface). Option B is incorrect because in common conductors, it is not the positively - charged particles (protons in the nucleus are not free to move in the same way as electrons in the conduction band) that move for current electricity.

Answer:

A. Negatively charged particles move from one point to another.
