That is related to the fact that the electrical forces are basically transmitted at the speed of light. This allows the current in a wire to travel at about 2/3 the speed of light in a vacuum, despite the fact that individual electrons move much slower than that (and the drift speed of a current is typically less than a millimeter per second). What happens here is simply that one electron (or other charge-carrier) transmit the energy to the next one, via electrical forces.
Current will flow as long as there is a difference of potential (a voltage) and a path for current to flow. So no power-control device is required for current flow but yes it will flow with a power control decive.
Everything Depends on the voltage supply ...... Current flow (Amp) = Watt / Voltage the Current flow will be 1 amp if voltage is 1 V the Current flow will be 0.5 amp if voltage is 2 V the Current flow will be 0.25 amp if voltage is 4 V and so on.......
A Counter-current flow has more advantages as comapared to a co-current flow.
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
Wires
Where the current is.
because the current
flow
the ability if a substance to slow down electric current
Tephra flow is fragments of volcanic rock and lava. Pyroclastic flow is fast moving current of hot gas and rock.
yes. a current can flow in a dead body but after 40 days the all the cells in body dead so after 4o days the current coudnot flow
Current means flow. Electric current means flow of electric charges Now there are two kind of charges. They are positive and negative But current is defined as the flow of positive charges But in metallic wires there is no chance for positive charges to flow through. Only loosely bound electrons with negative charge are capable of flowing. So current is case of metallic wire is due to electrons. So we have to assign as "conventional current". Conventional current is always opposite to the flow of electron flow Now from a battery current (conventional) flows right from positive polarity to the negative polarity. But within batter is has to flow right from negative to positive so as to complete the circuit of flow.
No voltage means no current can flow.

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.
Electric current is the rate of flow of electrons.AnswerA more accurate definition of electric current would be that it is a flow of electric charges. While current flow in a metallic conductor is, indeed, a flow of electrons, in other conductors -such as electrolytes- current flow may be a movement of ions. So, it would be more accurate to define current in terms of charge flow, rather than in terms of electron flow.
