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.

Is induction voltage ac or dc current?
Induction occurs only with alternating current.
Can inserting a resistor in a circuit have an effect similar to an open circuit?
If the resistance is large enough, then there might not be enough voltage difference to allow much current. Since, Voltage = Current * Resistance, if resistance goes really large, and your voltage doesn't change, your current must decrease. An open circuit is where you do not have any current flowing, so whether no current verses very little current is the same is up to you.
What 3 things does an electrical amplifier amplify?
An electrical amplifier amplifies 2 physical quantities according to the transistors used. If a BJT is used it amplifies the current and if a MOSFET is used it amplifies the voltage. Hybrid amplifiers amplify current as well as voltage so in theory , current voltage and power is amplified.
How much current flows in a 12 watt radio connected to 120 volt circuit?
A 120V household electrical outlet supplies 12 watts of powerwhen the current is 0.1 Ampere (and the power factor is 100%).
If Three 12 volt batteries are connected in parallel what is the effect on the circuit?
There will be no effect on the voltage. That is the effective voltage will be only 12 volt. But there will be increase of current.
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 is short circuit ratio?
Ratio of field current required to produce rated voltage in open circuit to the field current required to produce rated current in short circuit.
What voltage is needed to produce 6 A current through a resistance of 3?
18volts
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.
High voltage by itself does not produce electric shock What does?
The amount of current passing through your body and the path of the current.
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.
