Which of the following statements is true about the flow of electrons in an electric circuit?
A. Electrons always flow from lower to higher potential
B. Electrons always flow from higher to lower potential
C. Electrons flow from lower to higher potential except through power sources
D. Electrons flow from higher to lower potential, except through power sources
Solution
Force is the movement of charge. Ordinarily, our charges will be passed on by free-streaming electrons. Antagonistically charged electrons are held to particles of conductive materials.
Complete step by step solution:
In the event that the two necessities of an electric circuit are met, by then charge will travel through the external circuit. It is said that there is a current - a movement of charge. Using the word current in this setting is to simply use it to express that something is going on in the wires - the charge is moving. Anyway current is a real sum that can be assessed and conveyed numerically.
As a real sum, the current is the rate at which the charge streams past a point on a circuit. As depicted in the diagram under, the current in a circuit can be settled if the measure of charge Q experiencing a cross-part of a wire in a period t can be assessed. The current is basically the extent of the measure of charge and time.
Thus, the right answer is option (C).
Note:
Current is the flood of electrons, anyway current and electron stream the alternate way. Current streams from positive to negative and electron streams from negative to positive. Current is constrained by the quantity of electrons experiencing a cross-part of a conductor in one second.
