See voltage means potential difference. Electrons move from higher potential to lower potential always. In wire same thing happens. So electrons flow because there is potential difference and flow of electrons causes current to flow. current is nothing but flow of electrons. reply if u r satisfied @ rahul.khaladkar@rediffmail.com
What else can I help you with?
What is effect of voltage and current by changing the length of wire?
By changing the length of wire, say reducing it, the resistance will drop and that will increase current flow but the voltage is less likely to change V=IR.
How does the voltage applied to a circuit affect the current flowing through the wire?
Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.
Will 2.5mm wire conduct 240 volts?
You size wire by the current. Various insulations are rated for voltage, temperature and the medium where the wire will be run.
How was the current electricity produced?
ELECT. CURRENT IS BASICALLY THE FLOW OF ELECTRONS FROM ONE POINT TO ANOTHER POINT IN THE CIRCUIT. IN, AC IT IS "PUSHED" THROUGH THE WIRE BY THE MAGNETIZED COIL. ELECTRONS ARE AFFECTED BY MAGNETISM. IN DC, ON PART OF THE BATTERY HAS LESS ELECTRONS THAN THE OTHER. WHEN THESE TWO ARE CONNECTED, THE ELECTRONS FLOWS TO THE HUNGRIER ATOMS. THESE PRODUCES CURRENT OR ELECTRICITY IN THE WIRE.
What are the factors on which the heat produced the electric current depends upon?
It depends on1 the resistance of wire.2the voltage between the ends of the wire.3the flowing current time.
What creates a current of electricity in a wire?
A current of electricity is created in a wire when there is a potential difference (voltage) applied across the wire. The flow of electrons in response to this voltage creates the current. The movement of electrons is influenced by the properties of the material in the wire, such as its resistance and conductivity.
How is current carried through a wire?
Current is carried through a wire by the flow of electrons. When a voltage is applied across the wire, electrons move from the negative terminal to the positive terminal, creating an electric current. The movement of electrons creates an electric field along the wire, allowing for the flow of current.
How does ac current move in a wire?
AC current moves in a wire by periodically reversing direction, flowing back and forth in response to the alternating voltage source. The electrons in the wire oscillate back and forth, creating an electric field that propagates through the wire and carries the energy along with it.
Electric current in a copper wire is normally composed of what?
Electric current in a copper wire is composed of moving electrons. When a voltage is applied across the wire, the free electrons in the copper atoms move in response to the electric field, creating the flow of current.
What is the relationship between the speed of electrons in a wire and the flow of electric current?
The speed of electrons in a wire is typically very slow, but the flow of electric current is fast. This is because when a voltage is applied to a wire, it creates an electric field that pushes electrons along the wire, causing the flow of electric current.
What moves in a wire to make up current?
In the simplest form, the answer is ........ charge and energy. It is a common misconception that electrons are travelling around the circuit at a speed approaching that of light. Not true. While electron motion does occur due to alternating energy states in AC circuits, movement occurs in both directions. The net motion is therefore miniscule and may be ignored on a practical basis.
What do you mean by Polarity for the following Electrical parameters Charge Voltage Current Meter probes?
Charge, + charge is a lack of electrons, - is an excess of electrons, compared to a reference point. Voltage, + voltage is measured at a point that has a lack of electrons, compared to a reference point. Current, + current flowing through a wire indicates that electrons are flowing in the opposite direction Meter probes, see voltage above.
What is the electrical pressure that causes electrons to flow?
Voltage, measured in volts, is the electrical pressure that causes electrons to flow in a circuit. Voltage is what pushes electrons through a conductor, such as a wire, and is necessary for the flow of electrical current.
Why does electric current flow into circuits?
It may not be correct to say that an electric current will "flow into" circuits. Electrons move in a circuit in response to an applied voltage. And these electrons are alread in the circuit and available to support current flow if a voltage is applied. It may be more correct to say that electrons leave the negative terminal of a voltage source, and electrons enter the positive terminal of that voltage source. The electrons in the circuit that are availble to support current flow will "shift over" to create the current flow. Remember that the phenomenon of current flow in a wire is the "shifting over" of electrons in the wire. It's not about electrons going into one end of a wire and those same electrons coming out the other end. Use the link to the related question for more information that might help make things clearer.
Why increasing the voltage applied to a wire can have the same effect on the current in the wire that decreasing the resistance of the wire does?
Increasing the voltage applied to a wire will increase the electric field, which in turn accelerates the charge carriers (usually electrons) in the wire, leading to an increase in current. Similarly, decreasing the resistance of the wire allows more current to flow for the same voltage applied, achieving a similar effect of increasing the current. Both actions result in a greater flow of charge carriers through the wire.
What carries electricity through a wire?
Electricity is carried through a wire by the flow of electrons. When a voltage is applied across the wire, the electrons move in response to this, creating an electric current that can power devices or light bulbs.
How an electric current formed?
An electric current is formed when a flow of charged particles, usually electrons, moves through a conducting material such as a wire. This flow is generated by a voltage difference, which creates an electric field that pushes the charged particles through the conductor.
