Does voltage flow through a circuit or is it established across a circuit?
The 'charges' (electrons, in the case of a metal conductor) are ALREADY distributed within the conductor. They are in a state of constant, haphazard, movement at just short of the speed of light. When a potential difference is applied across the conductor, there is a tendency for these electrons to move from the negative potential towards the positive potential. This tendency is VERY slow; for example, an individual electron is unlikely to pass through the filament of a flashlight during the lifetime of its battery!
How do electrons work in a circuit?
1. heat. If it's hot enough, blackbody radiation (e.g. incandescent light bulb) 2. Electromagnetic radiation (radio waves, magnetic or electric coupling to adjacent conductors) if the current is changing.
How does a dc generator work?
By using a gas engine to drive a dc motor. Motors are cool in the way that if you give them power they will spin and if you spin them they will make power. There is a ball of coiled wire in a motor and when it spins the magnets in it try to resist the spinning but if it succeeds in spinning then electrons will be pushed through the coils by the resistance of the magnets and ultimately through your electrical appliance's.
What direction does electricity flow in a simple circuit?
This is a very complicated question in reality. in a simple Dc circuit (i.e. a battery driven circuit) there are 2 way's that current is talked about. the reason is historic, so here goes a very brief answer. When people first beagn to identify how current flowed in circuits there was a school of thought that a sort of liquid flowed in electric circuits, and the driver (battery) had parts that had an excess of the liquid, and parts that had less. The bits with more were positive + and the bits with less were lacking (negative) - Naturally the liquid would try to balance the circuit, and so current was said to flow from positive to neagtive. This is referred to as conventional current. so Conventional current is said to flow from positive to negative. Thanks to the work of Earnest Rutherford and Niels Bohr (a student of rutherford) we now know that electric current flows as a result of electrons in the wire bumping along the wire jumping from atom to atom. This actually means that in reality current should have been flowing from negative (a surplus store of electrons) to positive (a lack of electrons) to avoid confusion, a new term was coined. Electron Flow. so Electron Flow is from Negative to Positive. Now to your question. How does electricity flow in a simple circuit. A Battery has 2 plates, one charged with a surplus of electrons, and one lacking electrons. When a circuit is closed, the difference in the potential of the plates (called potential difference, and measured in Volts) causes electrons to be pushed into one end of the wire at the negative terminal, while a strong pull is made on the other end of the wire by the positive terminal. The electron at the negative terminal pushes its way onto the copper atom, making it's charge unbalance, so it lets one of its electrons go, this free electron, moves on the next atom ... and so on, literally bumping electrons along the wire in the direction of pull, created by the battery. finally an electron exists the wire into the battery and one electron has been transfered to balance the battery charge. The stronger the force (Voltage) the faster the electrons flow, this continues until the driving force (battery) is balanced (discharged) when we say the battery is flat. Hope this makes it a bit easier to understand what is happening, even if I can't exactly answer the question But I suspect your answer should be Electron Flow in a simple electrical circuit is from Negative to positive.
What does a thyristor works as a circuit breaker?
A thyristor is a type of semi-conductor and is used in a circuit to control the application of electrical power to a load. They are often found as the switching element in light dimmers and can be used as control elements in power supplies (variable or regulated). Types of thyristors are diacs, triacs, sidacs and SCRs (silicon controlled rectifier).
What makes electricity travel?
The flow of the electricity is being pushed through the circuit because of the electrons.
What supplies the electrons that will flow through the circuit?
The electrons that flow through a circuit come from the power source, such as a battery or generator. When the circuit is closed, the power source creates a potential difference that drives the flow of electrons through the circuit.
From which terminal of a battery are electrons pushed?
Electrons are pushed out from the negative terminal of a battery towards the positive terminal when a circuit is connected.
What pushes electrons in a electric circuit?
In an electric circuit, electrons are pushed by a voltage difference, also known as an electric potential difference. This voltage creates an electric field that exerts a force on the electrons, causing them to move through the circuit. The source of the voltage, such as a battery or power supply, creates this driving force for electron flow.
How is electricity energy carried around a circuit?
Electricity energy is carried around a circuit by the flow of electric charge, typically carried by electrons within a conductor such as a wire. When a voltage is applied, electrons are pushed through the circuit, creating a current that carries the energy from the power source to the load.
Where do electrons leave the battery?
Electrons leave the battery through the negative terminal, which is also referred to as the anode. As the chemical reaction within the battery generates electrical potential, electrons are pushed out of the negative terminal and flow through the external circuit to the positive terminal.
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 is the source of electrons in an ordinary electrical circuit is?
The electrons in an ordinary electrical circuit come from the atoms in the conductive material of the circuit, such as copper wires. When a voltage is applied, the electrons in the material are pushed and flow through the circuit, creating an electric current.
How does electricity flow through a light bulb?
Electricity flows through a light bulb when a voltage is applied to the bulb, causing current to pass through the filaments inside. The current heats up the filaments, which then emit light as a result of their high temperature.
What is used to measure how strongly the electrons in a wire are pushed?
Voltage is often referred to as Electro-Motive Force, or EMF. It is what causes current to flow in a conductor. Also called volt.
How much electricity does a 240 v use?
240 v doesn't use any electricity. v is a symbol for voltage which is one of the properties of electricity. How much is used is determind by load. 240 v simply is how much pressure the electrons are being pushed through the circuit with.
