What is the source of electrons that flow through a wire with a battery and light bulb connected in a simple circuit?

The electrons come from the metal of the wire, light bulb filament, and plates inside the battery. In other words, they are already everywhere in the circuit, even before it is connected together.
The electrons are made to move (and thus do work, e.g. heating the filament to make light) by the electromotive force generated by the corrosion of the metal plates inside the battery by the electrolyte between those plates.
Note: while the electric current flows around the circuit at a speed close to the speed of light, individual electrons within that current actually move very slowly due to the fact they keep bouncing off atoms and other electrons thus performing a "random walk". These speeds are on the order of millimeters per hour.

What is current in the battery called?
A battery contains a charge of electrons. When these electrons leave the battery and travel through a circuit that is described as current.
Examples of a circuit?
a circuit is a round wire that connects through a battery into a lightbulb
How does electricity flow from a battery through a circuit?
Not as you might think. Electricity flows FROM the negative pole, through the circuit, and then electrons flow into the positive pole.
What is the source of electrons that flow through the wire?
The battery or other power supply that energizes the circuit is.
What happens when a battery is hooked up to an open circuit?
nothings because they is no wire connected to the circuit so no current can flow through
What will the emf of battery if 2ohms and 3ohms are connected in series and a 5 ampere cureent is passing through the circuit connected?
1 volt
What is the iffrence between a series circuit and parallel circuit?
Series circuit: elements are connected one after the other; the current (the electrons, or other charge carriers) has to pass through each of the elements in turn. Parallel circuit: elements are connected in such a way that part of the current will pass through one circuit element, part through the other.
Almost all of the electrons flowing through a battery circuit come from what?
That question hurt my bobble sack.....
What is function of battery?
It stores electrical energy charge which then provides power to the circuit. Electricity is the stream of electrons through a conductive way like a wire. This way is known as a circuit. Batteries have three sections, an anode (- ), a cathode (+), and the electrolyte. The cathode and anode (the positive and negative sides at either end of a conventional battery) are snared to an electrical circuit.
When electric circuit is closed no current flow through it IS the statement is correct?
yes... this is possible if a diode i connected in reverse bias with a battery and a resistor for example. A diode in reverse bias means its anode will be connected to positive terminal of the battery and its cathode to the negative terminal of the battery. In such a case, minimal current flows through the circuit which can be neglected.
A closed path through which electrons can flow is?
A closed path through which electrons flow is known as a circuit.
What describes electricity flowing from a battery though a switch to a light bulb?
Circuit Electrons flow form the positive end of the battery through the wire connecting the positive terminal to a switch. The other end of the switch is connected to one terminal on the bulb, the other terminal of the bulb is connected to the negative end of the battery. No electrons (current) flows as long as the switch is open. Once the switch is closed and if the battery has enough voltage and current capacity to make the filament in the bulb glow, then the bulb emits light (together with wasted heat). If the switch is open, no current flows through the entire circuit and the bulb does not glow.
