Does voltage flow in a circuit Explain?
Voltage in an electrical circuit is the rough equivalent of pressure in a water pipe. It causes the electricity to flow. Higher voltage; more flow. The difference is that you can think of pressure applied at a single point, but voltage is always the difference in electrical potential between two points. That's how a bird can stand on a 7,000-volt rural electrical line without harm. The potential difference (voltage) between the line and the ground is 7,000 volts, but the potential difference (voltage) between the bird's two feet is very tiny.
Is it true that In Ohms law the variable i represents the rate of flow of charge which is called impedance?
"I" represents the current which is the flow of electric charge. Impedance is the measure of the opposition to the flow of current at a given voltage usually in a.c. circuits.
What does voltage cause the flow of?
there is a difference in electrical potential energy.
Difference between overcurrent relay and fuse?
Current is flow of electricity charge. Voltage is a measure of potential energy or charge. Fuse. Is a device that opens when the current rating is exceeded this stopping the flow of current.
What is the difference between current and electricity?
The word Current is a term used to describe the characteristics of electricity, the same way voltage and resistance are used. As an example: voltage is a difference in potental and is often considered the amount of pressure pushing an electrical charge or certain number of electrons through a conductor. This electrical charge is called current. Any conductor has resistance to the flow of charge or current. If for example a conductor has a resistance of 2 ohms and a voltage of 12 volts is applied the resulting current flowing in the circuit can be measured to be 6 ampere..the unit for current. Current is therefore, considered the intensity or amount of charge.Electricity then is the movement of this current of charge The word Current is a term used to describe the characteristics of electricity, the same way voltage and resistance are used.

For an electric current to flow the only thing needed is for two objects to have a difference in charge?
Actually, they need a difference in energy per charge. Voltage is energy per charge, in joules per coulomb, and a voltage differential is what is required to create an electric current flow.

Why do charges flow in wires?
Electronic charges will flow when a potential difference between the two locations, and an adequate path between them exists (with a low enough dielectric constant to allow the flow of charge - such as a wire). Electrons will move from here to there because there are "extra" electrons here, and there's some "missing" electrons there. Electrons have a specific charge. If you have "extra" electrons at one location relative to "missing" electrons at another location, you will have a negative voltage here, and a positive voltage (relative to here) there. This is called a potential difference (or voltage difference).
What condition will result in the flow of electric charge?
By the application of a voltage source electric charge will flow.
In what way does voltage help us?
Necessity ( or say function ) of voltage can be understood by the definition of voltage: Work required to be done ( or energy needed ) to move unit positive charge ( or electron ) from one point to another in the circuit is called voltage or the potential difference. Hence, it can be said that voltage helps in flow of current.
Which condition must exist between two points in a conductor in order to maintain a flow of charge?
a closed circuit
What is the flow of electrons callled?
The flow of electrons is called an electrical current. Current is measured in Amps and flows from a positive voltage towards a negative voltage. The electrons themselves have a negative charge so they move or flow in the opposite direction to the flow of current.
Is it true that In Ohms law the variable i represents the rate of flow of charge which is called impedance?
"I" represents the current which is the flow of electric charge. Impedance is the measure of the opposition to the flow of current at a given voltage usually in a.c. circuits.
Difference between voltage and current?
Voltage is electrical potential, measure in derived units of volts, which is joules per coulomb. Current is electrical flow, measured in derived units of amperes, which is coulombs per second. Stated in other terms, voltage is energy per charge, while current is charge per time. That makes power, or watts, equal to energy per time, and that is joules per second.If you think of the water system analogy, volts is sort of similar to pounds per square inch (though not completely so), while amperes is similar to gallons per minute.AnswerVoltage is synonymous with 'potential difference' -not potential- measured in volts. Current is the flow of electrical charge, measured in amperes. The volt is an SI derived unit, wheras an ampere is an SI base unit.
What is the flow of electricity charge?
it is the rate at which electric charges pass though a conductor. The charged particle can be either positive or negative. In order for a charge to flow, it needs a push (a force) and it is supplied by voltage, or potential difference. The charge flows from high potential energy to low potential energy.
What device uses the voltage in an electrical current?
A voltage, or potential difference, is what causes current to flow through a circuit. So all devices (called 'loads') require a voltage applied to them.
What does voltage cause the flow of?
there is a difference in electrical potential energy.
