Current is regulated by the resistance of the load. That said without voltage no current will flow. Both are intertwined, without all the components you have nothing. Refresh your self with Ohm's law. E = I x R, I = E/R, and R = E/I. E = Voltage, I = Amperage, R = Ohms resistance.Visualize it like a triangle, without all three sides you have nothing. Current is produced by lines of flux cutting through a conductor. Voltage is a measure of the force or power of the current produced.

ANSWER: VOLTS are just potential it can exist without current. The evidence of this potential is evident as soon as we try to measure it since current now have a path no matter how small or large. The load does not regulate the current flow but rather the potential does. If the potential disappear so does the current no matter what load there is.

Does copper need a voltage to produce a current?

Copper can not of itself produce a current. <><><><><> However, resistance, be it copper or some other material, will produce a current if a voltage is applied to it. The rule is Ohm's law: Current = Voltage divided by resistance.


How much voltage is needed to produce a current of 2 ampsthrough a resistance of 6 ohms?

12 voltage


Ac voltage applied across a load resistance produce alternating current?

The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.


Do Batteries produce electricity that is low voltage direct current?

Yes.


What voltage is needed to produce 6 A current through a resistance of 3?

18volts


What resistance would produce a current of 25 ampers?

resistance does not produce currents . you need source (like voltage source , current source ,or , discharging capacitor) to generate current .


How much voltage would be needed to produce a current that could be felt?

The voltage needed to produce a current that can be felt varies from person to person, but typically a voltage above 10 milliamperes can be felt by most individuals. Keep in mind that electrical current can be dangerous, and it is not recommended to intentionally expose oneself to electric shocks.


How does voltage produce current?

Voltage across two terminals mean there exists a potential difference, and when the circuit gets closed, due to this potential difference the current flow.


Why does a ac voltage applied across a load resistance produce alternating current in the circuit?

Because V = I x R or Voltage = Current x Resistance. Since resistance is linear there is a linear relationship between Current and voltage. If you have DC voltage you have DC current and if you have AC Voltage you have AC current. Note that there is a linguistic recognition of this relationship in that the voltage is described in terms of the current.


Why will a dc motor produce v but not an ac motor?

Motors do not produce voltage, current, or power. They use them.they produce mechanical output.


Why do electric company generators produce alternating current?

Because alternating current can be run through a transformer to step up or down the voltage. High voltage current incurs lower losses in transmission.
