Reverse current.
depending on the stray capacitance it can be from a few ten volts to a few kilo volts.
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.
no...current is a flow of electricity
Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.
voltage does not flow, current flowsAnswer'Voltage' is another word for 'potential difference' -you can think of it as being the equivalent of the difference in pressure across, say, the input and output ports of a central heating radiator which is responsible for pushing water to flow through that radiator. So 'voltage' exists across two points in a circuit, causing current to flow through the conductor between those two points.
voltage = the electrical "pressure"current = the electrical "movement rate" or "flow rate"
Voltage provides the "pressure" to push current "flow" through the circuit resistance.
In a water system, the "voltage" is the water pressure, the flow rate is the "current", and the pipe size is the "resistance". Low-voltage electrical current is equivalent to low-pressure water.
The pressure or force causing current to flow through a conductor is called voltage.
No, it is not true. An electrical current (which is a flow of electrons) can only flow from a higher pressure state (higher voltage) to a lower pressure state (lower voltage).
You apply a voltage across a load and the result is that a current flows through the load. So you must have the voltage present, the cause, before current flow, the effect. Think of voltage as pressure and current as flow.
depending on the stray capacitance it can be from a few ten volts to a few kilo volts.
Think of Voltage as the pressure and Amperage (current) as flow. If you think of it as pipes with water then the pressure would be voltage, and current would be how much water flows past a certain point in the pipe in a given time.

Current is defined as the rate of flow of charge through a body. ie, I = Q / T Voltage is the amount of Pressure needed to make the charge flow through the body. ie, V = J / Q A; current flow is not related to time if the EMF is constant the current flow will be constant. A1: current is electrons flow caused by the presence of EMF. A2: voltage is the EMF force necessary to make current or electrons to flow.
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.......
Voltage is what they are compared to.
