Solution
Para responder a la pregunta, vamos a analizar cada opción:
-
"carried by protons and electrons and is either positive or negative."
- Esta opción es incorrecta porque en un circuito eléctrico, la corriente es principalmente el flujo de electrones, no de protones.
-
"the movement of electrons around a circuit."
- Esta opción es correcta. La corriente eléctrica en un circuito es el movimiento de electrones a través de un conductor.
-
"a measure of how difficult it is for charges to move."
- Esta opción se refiere a la resistencia eléctrica, no a un circuito eléctrico en sí.
-
"a closed pathway made from a conducting material."
- Esta opción también es correcta. Un circuito eléctrico es un camino cerrado hecho de material conductor por donde pueden fluir los electrones.
Por lo tanto, las opciones correctas son la 2 y la 4.
