What controls the flow of electric current?
The flow of electric current is controlled by the voltage applied to a circuit. Voltage creates an electric field that pushes charged particles (electrons) through a conductor, allowing current to flow. The resistance in the circuit also affects the flow of current, as it determines how much opposition the current encounters.
What is 0.78 amps?
0.78 amps is a measure of electric current. It represents the flow of electric charge per unit of time. This value indicates how much current is passing through a circuit or device at a given time.
What does current mean in science?
It is probably used in the sense that current electricity is the opposite of static electricity. Current is a measure of the movement of electric charges, while in static electricity the charges do not move much.
What is an unit that tells how much electric current flow through a wire?
amperes or A.
Is an electric current a movement of electrons at near the speed of light?
No, electric current is the flow of electrons through a conductor, but the individual electrons do not move at near the speed of light. Instead, the speed of electron movement in a conductor is typically much slower.
What controls the flow of electric current?

Voltage creates an electric field that pushes charged particles (electrons) through a conductor, allowing current to flow. The resistance in the circuit also affects the flow of current, as it determines how much opposition the current encounters.
Resistance to current flow is measured in?
Resistance to current flow is measured in ohms, denoted by the symbol Ω. It quantifies how much a material or component impedes the flow of electric current through it.
What is it called when you measure of how much electrical energy carries electrons?
Electron flow is current, or coulombs per second. Electron potential is voltage or joules per second.
What is the rate of a flow charge?
The rate of flow charge, commonly known as the current, is measured in amperes (A) and represents the amount of electric charge passing through a given point in a circuit per unit of time. It is the flow of electric charge carriers, such as electrons, in a circuit and is essential for the operation of electrical devices.
In an electric circuit resistance is?
Resistance is the opposition to the flow of electric current through a conductor. It is defined as the ratio of the potential difference (volts) between the ends of the conductor to the magnitude of the current (amps) through the conductor.
What is 0.78 amps?
0.78 amps is a measure of electric current. It represents the flow of electric charge per unit of time. This value indicates how much current is passing through a circuit or device at a given time.
What does current mean in science?
It is probably used in the sense that current electricity is the opposite of static electricity. Current is a measure of the movement of electric charges, while in static electricity the charges do not move much.
What is the difference between an ampere and an ohm?
An ampere (A) is a unit of electric current, measuring the rate of flow of electric charge. Ohm (Ω) is a unit of electrical resistance, measuring how much a material resists the flow of current. In simple terms, amps measure the flow of electricity, while ohms measure the resistance to that flow.
What does ohm mean in physics?
In physics, ohm (symbol Ω) is the unit of electrical resistance. It is used to measure how much a material opposes the flow of electric current. One ohm is equal to the resistance that allows one ampere of current to flow when one volt of electric potential is applied across it.
What are Ohms the measurement of?
Ohms are the unit of measurement for electrical resistance. It indicates how much a material resists the flow of electric current.
Why is the flow of electric current opposite to the flow of electrons?
Because much of the theory of electricity was developed before scientists realised that it was not a moving positive charge that was responsible but a negative one (of the electron).
What is meant by electric resistance of a conductor?
Electric resistance is a measure of how much a material impedes the flow of electrical current. It is denoted by the symbol R and is measured in Ohms. Conductors with higher resistance require more energy to push current through them.
