Voltage across two terminals mean there exists a potential difference, and when the circuit gets closed, due to this potential difference the current flow.
What else can I help you with?
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 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 .
What voltage is needed to produce 6 A current through a resistance of 3?
18volts
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.
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.
The voltage needed to produce a current of 8 A in a resistance of 12 ohms is?
8x12=96
Calculate the voltage required to produce a current of 2.0 A in a wire with a resistance of 16?
32v
