A movement of charges in response to a potential difference is called what?

The movement of charges in response to a potential difference is called an electric current. This flow of charged particles creates an electric field and is the basis for the operation of electrical circuits.


Electricity is due to the behavior of tiny particles called?

Electricity is due to the behavior of tiny particles called electrons. Electrons are negatively charged particles that flow through conductive materials in response to a potential difference, creating an electric current.


Describe how muscle cells can generate potential difference?

Muscle cells generate potential difference through the movement of charged ions across their membrane. This is achieved by opening and closing ion channels in response to stimuli, such as nerve signals or changes in membrane potential. The movement of ions, such as sodium and potassium, creates an imbalance in charge that results in a potential difference across the cell membrane, which is essential for muscle contraction.


What stimulus below this intensity will result in no response in a neuron?

Any stimulus below the neuron's threshold potential will not result in a response, as it is not strong enough to generate an action potential. Neurons require a minimum level of stimulus intensity to reach the threshold potential and fire an action potential.


The response of a motor unit to a single action potential of its motor neuron is called?

The response of a motor unit to a single action potential of its motor neuron is called a muscle twitch. This involves the contraction of all the muscle fibers within the motor unit in response to the stimulation from the motor neuron.

What causes an electric current?

An electric current is caused by the flow of charged particles, typically electrons, through a conductor. When there is a potential difference (voltage) applied across a conductor, the free electrons will move in response to this voltage, creating a flow of electric current.


When a steady potential difference is applied across the ends of a conducting wire?

Current flows through the wire due to the movement of free electrons within the material, in response to the electric field established by the potential difference. The current is directly proportional to the applied potential difference, as described by Ohm's Law, provided the material's resistance remains constant.


What is the definition of particle motion?

Particle motion refers to the movement of individual particles in a substance or medium, such as the movement of atoms or molecules in a gas or liquid. It can also refer to the motion of subatomic particles in nuclear reactions or the movement of particles in response to external forces like electromagnetic fields.

What causes charges to move in a curciut?

Charges move in a circuit due to the presence of an electric field established by a potential difference (voltage) between two points in the circuit. This electric field exerts a force on the charges, causing them to flow in response to the potential difference and complete a closed loop.


How does potential difference induce an electric current?

A potential difference, or voltage, creates an electric field along a conductor. This electric field exerts a force on the free electrons within the conductor, causing them to move in response to the voltage. This movement of electrons constitutes an electric current flowing through the conductor.


What force makes electrons move?

Electrons move in response to an electric force, which is generated by a difference in electric potential. This force causes electrons to flow from areas of high potential (positive) to areas of low potential (negative), creating an electric current.


What is the difference between generator potential and action potential in terms of their roles in the nervous system?

Generator potential is a small electrical signal that occurs in response to a stimulus, while action potential is a larger electrical signal that is responsible for transmitting signals along the nerve cell. Generator potential initiates the process of creating an action potential, which then allows for the transmission of signals within the nervous system.
