What potential difference is required to cause 4.00 A to flow through a resistance of 330 ohm?

Ohm's Law: Voltage = current times resistance
4 amperes times 330 ohms = 1320 volts
However, this represents a power of 5280 watts, and the resistor will get very, very hot. As a result, temperature coefficient will enter into the equation, and the resulting resistance will probably be higher than expected.

When the current traveling through a resistor is increased what happens to the voltage that travels through the same resistor?
Your question reveals fundamental misunderstandings about the nature of electricity.'Voltage' is simply another word for 'potential difference', and a potential difference appears across opposite ends of the resistor; it doesn't 'travel through' that resistor! Current, on the other hand, DOES 'travel through' the resistor and is caused by the potential difference across the resistor.Resistance is the ratio of potential difference to current. So if the resistance remians unchanged when the current through it doubles, then it has happened because the potential difference has doubled.
What is the potential difference neede to send 2a through a 5 ohms resistor?
V=I*R -- Potential (Voltage, V) = Current (Amperage, I) * Resistance (Ohms)2A*5Ohms = 10V
8 If the resistance of an electric circuit is 12 ohms and the voltage in the circuit is 60 V the current flowing through the circuit is?
There is a simple equation relating voltage (properly potential difference), current and resistance: V=IR Where V=potential difference, I=current and R=resistance So to answer: I=60/12 I=5
When the potential is high the current passing through a conductor it is also high true or false?
I think you mean when the 'potential difference' is high, is the current also high? The answer is that it depends on the impedance (a.c.) or resistance (d.c.) of the circuit. If this remains constant, then raising the potential difference will cause the current to increase too.
What do you use to measure electricity?
In an electrical circuit there is a flow of electrons. The flow is induced by the creation at a production station, battery, or other supply of an "Electromotive Force (E)". The size of the electromotive force is measured in "Volts". The rate of flow of the electrons through the circuit is called the "Current (I)". Current is measured in "Amperes". The typical conductor for transporting electrons through a circuit is wire and the smaller the diameter of the wire the more the "Resistance(R)" to the flow; the larger the diameter, the less the resistance. Resistance is measured in OHMS. Definitions of volt, ampere, and ohm: 1 volt: Electromotive force required to send a current of 1 ampere through a system in which the resistance measures 1 ohm. 1 ampere: Rate of flow of electrons in a system in which the electromotive force is 1 volt and the resistance, 1 ohm. 1 ohm: Resistance offered by a system in which the electromotive force is 1 volt and the current, 1 ampere.(Found at http://www.tpub.com/content/engineering/14069/css/14069_52.htm)
What is the circuit produced by a potential difference of 240 colts through a resistance of 0.2 ohms?
1200
What will be the potential difference across a 50Ω resistor if a current of 500mA is flowing through it?
Potential difference equals current multiplied by resistance or E = IR therefore the answer to your question is 25 volts
What is the difference between resistance and resistor?
Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it. A resistor is a electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.. depending on how much current you want to pass through a circuit, you would design the circuit with the required resistors

Why is the potential difference between two points in a good conductor so small that it can be neglected?
Potential difference V = I R. Here I is the current passing through the conductor. R is the resistance of the conductor. In case of good conductor the resistance will be almost zero and so the product too becomes almost zero. Hence the potential difference is neglected.
In an electric circuit resistance is?
Resistance is the opposition to the flow of electric current through a conductor. It is defined as the ratio of the potential difference (volts) between the ends of the conductor to the magnitude of the current (amps) through the conductor.
How the declair one ohm resistance?
One ohm is the resistance through which a current of one ampere will induce an electrical potential difference of one volt. Ohm's Law: Resistance is Voltage divided by Current

One way to make current is to use a what?
You can apply a potential difference across a wire to cause a current to flow through. Ohm's Law allows you to calculate the amount of current based on the voltage supplied and the resistance of the circuit. I = current V = voltage or potential difference R = resistance I = V/R
