What is the difference between power and current?
It's the difference between pressure and flow. The pressure is measured in volts, and the current in amps.Current is the flow of electrons.Power=VIcosϕV=voltageI=currentCosϕ=cosine of angle between V and IAnswerCurrent is a drift of electric charge, expressed in amperes. Power is the rate of doing work, expressed in watts (equivalent to a joule per second).
What is the Difference between dielectric and insulator?
The difference between dielectric and insulator lies in its field of application.Dielectrics are used to store the electric charges, while insulators are used to block the flow of electric charges ( they more or less act like a wall).While all dielectrics are insulators (they don't allow the flow of electric charges through them) all insulators aren't dielectric because they can't store charges unlike dielectrics.
Is electric current and current the same thing?
Not really. You can compare them with the analogy of water flowing through a pipe. For water to flow, there must be a pressure difference across the ends of the pipe. An electric current is a movement of electric charges along a conductor. For those charges to move, there must be a voltage (more accurately, a 'potential difference') across the ends of the conductor. So a potential difference is required to cause current to flow.
Do charges move from a source of potential difference into a load or through both the source and the load?
As the circuit must be a closed loop, the current passes through both the source and load. If it was not a closed loop no current could flow anywhere.
What are two of the main requirements that allow electric charge to flow in an electric circuit?
In order to have a valid electric circuit, two requirements must be met: there must be a potential difference within it (measured in Volts), and current must be flowing through it (measured in Amperes). That implies that the three basic blocks of a circuit are present - a power source (that defines the potential and supplies the current), conductors (which connect the power source to the load), and the load, which consumes current to do some work. Coincidentally, lack of a potential difference means that there are no charges "willing" to travel between point A and point B, which means that there is no current flowing from A to B (or otherwise), in regard to just these two measurement points. Of course, if you connect just your voltmeter to a battery, you will see a readout - that is because the voltmeter completes the circuit (and is doing some work for you), and since the circuit is complete, the current is flowing, and that implies a difference of potential.
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.
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.
Can there be a potential difference between two conductors that carry like charges of the same magnitude?
no there cant
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.
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')
What is the net field midway between the two identical negative charge?
Electric field at the mid point between the two identical negative charges will be zero. In the same way, if both charges are of identical positive, the field at the mid way will be zero.
What is necessary for charges to flow between two points?
Either potential difference (apply voltage) or energy input (drag the charged particle)
Does a voltage have one terminal?
No. Voltage is the potential difference in energy between two charges. (Volts is joules per coulomb.) Since it is potential, that means it is relative, and in order to be relative, there must be two terminals.
What is the definition of atomic charges?
The difference between the positive charges (protons) and the negative charges (electrons).
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.
