What is a difference in electric charge called?
The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
What influences the movement of ions and molecules across cell membranes?
A membrane potential is basically the difference between the inside and outside of the cell. Ions are charged, and so will change the membrane potential (the difference between charges on the inside and outside) when they move. Please see the related link below which includes a diagram of how ions affect membrane potential.
What is the flow of an electrical current in a circuit outside the power source?
Usually a circuit is connected to a power source, which could be a battery or an outlet. When this happens current flows through the circuit. The power supply raises electrical charges through the required potential difference, and then in the circuit the charges flow down the potential gradient giving up their energy.
Why do charges flow in wires?
Electronic charges will flow when a potential difference between the two locations, and an adequate path between them exists (with a low enough dielectric constant to allow the flow of charge - such as a wire). Electrons will move from here to there because there are "extra" electrons here, and there's some "missing" electrons there. Electrons have a specific charge. If you have "extra" electrons at one location relative to "missing" electrons at another location, you will have a negative voltage here, and a positive voltage (relative to here) there. This is called a potential difference (or voltage difference).
Is it possible that the potential of a body is decreasing but charge over it remains constant?
No, it is not possible if the body is of a fixed dimension and the charges are electrostatic. The potential of a body is directly proportional to the charge on it. If the body is experiencing decreasing potential, it is because charges are being transferred. The charge is changing to effect the change of potential. If a given electrostatic potential is assigned to a balloon, and charges are being transferred as air is let out of the balloon, it is possible to achieve a decrease of potential while maintaining a constant charge density on the surface of the balloon, but that's afield of the question. Charges must be transferred to effect any change in potential, so overall charge will change as potential changes in a body under consideration.
How much potential difference is there between two identical charges?
There is no potential difference between identical charges
What is it called when positive and negative charges have a potential difference?
Voltage.
A what difference is the what that causes charges to move?
. . . potential or voltage . . . . . . pressure
Do charges in an electric circuit flow because of a difference in electrical potential energy?
"voltage" (also referred to as 'potential')
How can you get the largest voltage difference?
There is no such thing as a 'voltage difference'! 'Voltage' means 'potential difference', so what you appear to be asking is "How do you get the largest potential difference difference?'! Potential difference is caused by the separation of charges between two points. The greater the amount of charge separation, the greater the potential difference.
How do you create a potential difference?
Potential difference arises between two conductors when there is a difference in the charge content between them. So, to create it u can take out or pump in charges, which is the job done by a battery.
Is the weak nuclear force associated with static cling?
No, the weak nuclear force is not associated with static cling. It is the electromagnetic force that is responsible for static cling. Static cling is the result of the movement of electrical charges, and the difference in electrostatic potential that happens when charges move is what attracts things.
Can there be a potential difference between two conductors that carry like charges of the same magnitude?
no there cant
Do charges move around a circuit due to electrostatic forces or potential difference?
Yes to both.
What is th potential difference that causes charges to move in a circuit?
The answer is voltage, resistance, electric discharge, and current. It is caused by a difference in energy stability between two points that favors a charge to move down a potential difference.
