Which statement correctly describes the formation of an electric current?
a resistance causes electric charges to move from lower to higher potential.
a voltage causes electric charges to move from lower to higher potential.
a resistance causes electric charges to move from higher to lower potential.
a voltage causes electric charges to move from higher to lower potential.

The correct answer to the question is D) A voltage causes electric charges to move from higher to lower potential.

EXPLANATION:

The flow of charge is similar to the flow of heat. Heat flows from a body at higher temperature to a body at lower temperature. Just like heat, the charge flows from higher potential to lower potential.

The potential difference across the two ends of a conductor is the sole cause for the flow of charge. When charge flows through a conductor or any devices, it will constitute electric current.

Resistance is the opposition to the flow of current. More is the resistance, the lesser will be the current. Resistance plays no role in creating the motion in charges . It only reduces the amount of current in a circuit.

Hence, the correct answer to the question is - A voltage causes the electric charges to move from higher to lower potential.

truck y has a greater velocity than truck x.

i think its c if i'm wrong
