Free electrons are in a constant state of chaotic movement in all directions. Under the influence of an external electric field, the continue to move in all directions, but there is a bias in one direction. So when we describe an electric current, the movement of individual electrons along a conductor is V-E-R-Y slow. So slow, in fact, that an individual electron is unlikely to pass through the filament of a flashlight before its battery has expired!
electric current
Yes
There is a potential difference (voltage) between two points and a path for electrons to travel from an area of low potential (negative) to an area of high potential (positive). Note the direction of "current flow" is opposite the direction of electron flow. In other words current flows from positive to negative. In a circuit involving only a resistor, the current flowing in the circuit is given by I=V/R where I = current, V= voltage, and R=resistance.
yes
The electric current moves in the direction opposite to the flow of electrons by convention.When a potential difference is applied to a material which has "loose" electrons, the electrons move in a direction opposite to the potential gradient and the current moves in the opposite direction to the flow of electrons.This is how current flows in materials.
Positive electrical flow is electrons flowing in one direction in a wire, if they change the direction of flow that would be a negative flow. If they change direction quickly, say 60 times a second, that would be alternating current, which is what we have in the united states as household electricity.
always current flow from the opposite direction of electron
Yes. Electrical current only flows in a closed circuit. If it were an open circuit, there would be no current.AnswerAn interesting question. The answer is.... not necessarily! I say this because a capacitor is an open circuit, yet it allows d.c. current to flow for a short period of time (while it charges), and it allows a.c. current to flow continuously.
It flows from higher potential to lower potential. simply opposite to direction of electrons flow...
It is a flow of electrons.
A closed path through which electrons flow is known as a circuit.
an open circuit allows electrons to flow constantly
The current in each branch of the circuit will turn and flow in the other direction.
They reduce the flow of electrons.
what is all conditions which limit the flow of electrons in an electric circuit? A resistor
In order to have the electricity or the flow or electrons going around the circuit, the circuit must be closed. If it is not closed then electrons cannot flow.
No, the electrons just starts flowing across the closed circuit, in the direction opposite to the flow of currentIt is confusing to say that 'electrons flow in the opposite direction to current' because, in metal conductors, current is a flow of electrons! 'Conventional flow', which is being referred to, here, is simply a convention and doesn't represent real current flow. Considering how long we have known about electrons, it's really about time we abandoned 'conventional flow'.
