To determine

To explain: The cause for the movement of electrons through a wire.

Answer to Problem 3CQ

The cause for the movement of electrons through a wire is the potential difference.

Explanation of Solution

The electrons in a wire (conductor) moves from one terminal to the other when it is connected to a battery. The battery provides the potential difference in order to move the electrons from lower potential to the higher potential and subsequently establish the electrical field.

The electrical potential difference points the electrical field from higher potential towards lower potential.

The flow of electrons from lower potential to the higher potential in a conductor causes the flow of current from higher potential to the lower potential.

Conclusion:

Thus, the cause for the movement of electrons through a wire is the potential difference.

A woman is touching a Van de Graaff generator which causes her hair to stick on end. Is the current high? Is the voltage high? Why is she not electrocuted?
there are 34 x 10^19 electrons that passes through a point in 3 seconds, what is the current?
Why is it economical to use extremely high voltages for the transmission of electrical power?       High voltage and lower current implies that the electricity can travel longer distances.     High voltage and lower current implies that the wires used can be thinner.     High voltage and lower current implies that the power loss (ohmic heating) due to resistance is low as well.     High voltage and lower current implies that the power plant can generate electricity more easily.     High voltage and lower current implies that the resistance is higher, leading to a smaller power loss.     High voltage and lower current implies that the amount of power generated per minute is very high, therefore rendering the method very efficient
