Question

electric current is the flow of charged particles called ______
○ protons.
○ electrons.
○ sparks.
○ static.

Explanation:

In physics (a subfield of Natural Science), electric current is defined as the flow of charged particles. Electrons are negatively charged particles that move in a circuit to create electric current. Protons are generally bound in atomic nuclei and do not flow freely to form current. Sparks are a discharge phenomenon, not the charged particles themselves. Static refers to static electricity, not the particles causing current flow. So the correct charged particles for electric current flow are electrons.

Answer:

B. electrons.
