The polarity of an electric current indicates what?

Its voltage
Its speed
Its strength
Negative/Positive pole

The correct answer is: Negative/Positive pole

An electric current can be either positive or negative, but without context or a reference, it is difficult to determine which one it is. The polarity of an electric current refers to the direction of the flow of electrons within the current. This can be determined by identifying the negative and positive poles of the circuit. Options A, B, and C are incorrect as they describe different aspects of an electric current that do not relate to its polarity.
