the amount of stuff in it makes it do stuff like voltage.
ANSWER: In the sky particles motion creates a potential magnetics and motion will do the same thing.
Separation of electric charges (eg by a moving magnetic field as in a dynamo). The more you separate them the higher the voltage. There are chemical ways of doing it, as in a battery.
What else can I help you with?
A device that creates a potential difference in an electric circuit is?
It is called power supply or battery.
When current flows in a conductor a magnetic field is created. The created magnetic field cuts the conductor which creates a voltage in the conductor. What is this voltage called?
It's called back EMF or reverse EMF. The EMF is electro-motive force, or voltage. What is happening is that the original current flow creates a magnetic field. That field then induces a voltage that opposes the original voltage that is causing the current flow. This back EMF "resists" the original voltage's efforts to cause current flow. If the created magnetic field did not oppose the original "efforts" of the voltage source to make current flow, then it would aid that voltage to make current flow. We would then get something for nothing and perpetual motion would be possible. We can't do that.
What does voltage across a conductor do?
Voltage across a conductor creates an electric field that causes free electrons to move, resulting in an electric current. This potential difference drives the flow of charge carriers, allowing electrical energy to be transmitted through the conductor. The amount of current that flows is directly proportional to the voltage applied, as described by Ohm's Law. In essence, voltage is the force that pushes electrons through a circuit.
What is the difference between voltage forward voltage and voltage drop?
Voltage is the potential difference between the source & any point in the circuit. The forward voltage is the voltage drop across the diode if the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode). Voltage drop means, amount of voltage by which voltage across load resistor is less then the source voltage.
What is voltage gain?
Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.
What is such as battery that creates a potential energy difference in a circuit?
A battery creates a potential energy difference by separating positive and negative charges to create a voltage. This voltage difference creates an electric field that drives the flow of charged particles (current) through the circuit.
Will a photocell work using dc voltage?
it creates a dc current
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.
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.
A device that creates a potential difference in an electric circuit is?
It is called power supply or battery.
What direction do electrons move?
Electrons typically move from areas of higher voltage to areas of lower voltage, following the path of least resistance in a circuit. This movement creates an electric current.
Changing the voltage or current in a circuit creates?
Changing the voltage or current in a circuit creates variations in electrical power and can affect the performance of the connected components. Increased voltage can lead to higher current flow, potentially causing components to overheat or become damaged if they exceed their rated limits. Conversely, lowering voltage or current can reduce the power delivered to devices, potentially causing them to operate inefficiently or fail to function. Overall, adjustments in voltage and current impact the circuit's functionality and the safety of the components involved.
How does an ammeter work?
An ammeter is a low voltage voltmeter in parallel with a small resistance resistor. Current flow through the resistor creates a voltage drop across it which is then measured by the voltmeter.
When current flows in a conductor a magnetic field is created. The created magnetic field cuts the conductor which creates a voltage in the conductor. What is this voltage called?
It's called back EMF or reverse EMF. The EMF is electro-motive force, or voltage. What is happening is that the original current flow creates a magnetic field.

What is alternator?
It is a device that converts mechanical energy to electrical energy on a car. It works by:the alternator creates an electric field by spinning a magnetic rotor with direct current inside stator windings. an ac voltage is developed and rectified dc. this voltage is compared to the battery voltage and determines the current through the rotor. if the battery voltage is lower than the alternator voltage, more current through the rotor increases the magnetic field and creates a larger alternator voltage. if the battery voltage is higher, less current through the rotor decreases the alternator voltage.
What creates an electric force field that moves electrons through a circuit?
An electric potential difference, also known as voltage, creates an electric force field that moves electrons through a circuit. Electrons flow from areas of high potential (voltage) to areas of low potential, creating an electric current in the circuit.
What force pushes electrical current through wires and conductors?
Voltage is the force that pushes electrical current through wires and conductors. It creates an electrical pressure that drives the flow of electrons from areas of higher voltage to areas of lower voltage. This difference in voltage is what causes the electrical current to move through the circuit.
