What is a series circuit that is used to produce a voltage source of desired magnitude from a higher voltage battery?

Such a circuit would be called a voltage divider.
The circuit would consist of two or more resistors in series across a battery or other voltage source. Each resistor would drop a certain amount of voltage (proportional to its resistance), and by considering the voltage drops, the investigator could pick two points in the circuit from which to take (or "pick off") the desired voltage needed for a project. Let's look at just one example.
If a 12 volt battery has two 1K ohm resistors in series across it, each resistor will drop 6 volts. By connecting wires from each end of one resistor, the 6 volts can be "picked off" and used to do something else. Certainly there are limitations concerning how much current can be drawn from the circuit (called loading the circuit), as the "diversion" of current around the resistor that is providing the voltage will change the voltage that is being picked off. But for small amounts of current, the voltage divider will work adequately.

What can be used to produce a continuous flow of charge?
A battery will do this, when connected to a closed circuit (for a while).
Why can a car battery have an open-circuit terminal voltage of twelve volts but be unable to start the car and thus be considered dead?
A fully charged cell in a car battery produces 2.2 volts, there are 6 cells in a battery. That would make true open circuit voltage on a fully charged battery at 13.2 volts. So a 12 volt open circuit reading is a discharged battery. The battery can have enough chemical reaction to produce voltage but not enough potential or power to crank the engine. Think about a fresh 9 volt battery. It is big enough to produce 9 volts, but not enough to crank a car or even light the dome light dimly. A car battery wears out slowly from the time it is purchased. Eventually it doesn't have enough power or amperage left to operate the car.
What is short circuit ratio?
Ratio of field current required to produce rated voltage in open circuit to the field current required to produce rated current in short circuit.
What would the current be if an extra battery was added to a circuit?
If you add more batteries in series, the voltage would increase. This would drastically change the circuit. Normally this should also produce more current.The effect of adding more batteries in parallel is insignificant for many circuits. Adding more batteries in parallel is like lowering a battery's internal resistance - which, for many circuits, can be neglected.Example: The battery's internal resistance can be neglected; the battery gives a voltage of 12 volt, you connect it to a resistance of 2 ohm. According to Ohm's law, that will give you a current of 6 ampere. Note that the battery capacity does not enter the calculation! Adding a second battery (of the same kind) will produce the same voltage, thus, the same current.If you add more batteries in series, the voltage would increase.

Why differentiator only produce a square wave?
It doesn't. It can produce any waveform if you feed the integral of the desired waveform into the differentiator's input.
What can be used to produce a continuous flow of charge?
A battery will do this, when connected to a closed circuit (for a while).
What part of a circuit is the light bulb?
It has components that are arranged end to end in order to produce light.
If in a circuit why do batteries die?
Batteries produce electricity by chemical reaction. When all the chemicals in the battery are used up, the reaction can't continue and the battery dies.
Is a battery an example of a conductor?
The outside of the battery is an insulator, but inside it's a conductor.
How does a battery produce life?
A battery does and can not produce life.
How do you charge a battery using dynamo?
A "Dynamo" is a DC charger; these will overcharge any battery there is and requires a regulator circuit, they will produce voltage proportional to their rotation. Simply hook it to the battery (watch your positive and negative) and crank the generator / dynamo.
Does a battery supply the electrons in an electric circuit?
No, is it incorrect to say that a battery produces the charges that circulate in a circuit. Some might suggest that a battery is a current source, but the battery should most properly be considered a voltage source. It generates the electromotive force (emf or voltage) that causes charges to move. (It does this through electrochemical reactions.) The charges that circulate in a circuit (which might be termed the current flow) are already in the conductor and components. All the battery does is produce the voltage (the force) to move charges. Let's look at current flow and see why things might be best looked at in the manner we've stated.Note that the way a battery moves charges is to "inject" an electron into the circuit where it is tied to the negative terminal of that battery. The electron causes one electron in the circuit at the terminal to "move over" and that will cause another electron to "move over" and so on. This will continue until the "last electron" in the circuit at the positive terminal of the battery leaves the circuit and "goes into" the battery. Current flow in the circuit is like musical chairs with electrons everywhere in the circuit "moving over a space" to cause the current flow.Having gone through all that, it should be easier to see why a battery probably should not be considered the producer of charges that circulate in a circuit. Rather, the battery is the source of the voltage that drives the charges (the current) in the circuit.
What form of energy does the battery produce?
Batteries produce energy using a chemical reaction with electrolytes
What does a battery use to produce electricity?
a battery has potential ( voltage). without a circuit atatched to it nothing happens. But when used in an electic ciruit, like with a light bulb, current will flow(amps). current flow is what causes your light bulb to light. A battery has the pressure (voltage) so to speak to cause current flow. Generally, current flows from negative to positive ina complete circuit.

What is limiter circuit?
Limiting circuits use 'clippers' to keep the input power within a set range in case of AC or below a set power level in DC circuitry. The limiting property of the circuit is that it modifies the input to produce a signal that is within a desired range.
