Question

In a D.C circuit when a switch is closed to operate the circuit, the electrons that cause the current:
(A) travel from the negative plate of the battery to the positive plate
(B) travel from the positive plate of the battery to the negative plate
(C) travel from one resistance to the next resistance
(D) travel from the negative plate of the battery to the positive plate inside the battery
(E) travel from one atom in the circuit to the next atom

Answer 1

Hint: The particles which carry charge through the wires in a circuit are mobile electrons. The electric field direction within a circuit is the direction that positive test charges are moved. Thus, the negatively charged electron moves in the direction of the opposite to the electric field.

Complete step by step answer:
The flow of current is always from the positive terminal or plate to the negative terminal or the plate. The charges always flow from the higher potential energy to lower potential energy. So, the charge of current in a circuit flows in only one direction. Unlike the alternating current, the flow of direct current does not change periodically. The current electricity flows in a single direction in the circuit at a steady voltage. The major use of DC current is to supply the power for electrical devices and also to charge batteries. Example: Mobile phone batteries, flashlights, flat-screen television, and electric vehicles. DC has a combination of positive and negative signs.

Everything that runs on a battery and uses an AC adapter while plugging into a wall or uses a USB cable for power relies on DC. Examples would be cell phones, electric vehicles, flashlights, flat-screen TVs (AC goes into the TV and is converted into DC).

Hence, we can say that option (A) is the correct answer.

Note:
In a D.C circuit when a switch is closed to operate the circuit, the electrons that cause the current travel from the negative plate of the battery to the positive plate, which is because of the current flow from high potential to the low potential.
