Use the following information to answer the next question.
The given figure shows a circuit with a resistor R connected to a cell of voltage V.
Which statement is correct regarding the flow of charges through resistor R?
The correct option is D Only electrons travel from Q to P, while no flow of protons takes place
Current flows from higher potential to lower potential. Point P is at higher potential, since it is connected to the positive terminal of the cell, as compared to point Q. Therefore, current flows from P to Q through resistance R. It is a conventional consideration that the direction of flow of electrons is opposite to the direction of flow of current. Therefore, the direction of flow of electrons inside resistor R is from Q to P. Furthermore, it is known that protons do not move in a conductor because they are fixed charges.
