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 metals making up the circuit contain electrons themselves, and when they are together they form a conduction band (a 'sea' of delocalised electrons moving freely around positive atomic kernels) between the bonded metals. So no electrons are actually 'poured in', they are just pushed around.
How does electricity flow through a light bulb?
The atoms inside the wire of the lightbulb all have electrons which are pushed from atom to atom when the light is turned on, this is the current. When the electrons are pushed around the circuit they generate lots of heat because the wire in the bulb is so thin, this makes the wire glow white hot which creates the light.
From which terminal of a battery are electrons pushed?
electrons come from the negative terminal, then goes around the complete circuit (clockwise) and comes back to the positive terminal. hope that helps!
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.

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.
What causes a flashlight to turn on when the button is pushed?
pushing the button changes the circuit from a series circuit to a parallel circuit.

What is needed to push the electrons from the cathode to anode?
Actually the electrons are pulled not pushed. The anode attracts them with its positive charge.
Are electrons pushed more strongly in an electric stove or in a light bulb?
No
What happen to the food inside the small intestine?
Pretty much nothing, chemically speaking. They get pushed through the system along with everything else through peristalsis and are eventually excreted.
