This is Ohm's law. It says that voltage (E) equals current (I) times resistance (R). It can be written three ways, and here they are: E = I x R I = E / R R = E / I Voltage and current are directly proportional. What happens to one will happen to the other. What this says is that for a fixed resistance, increasing the voltage will cause an increase in current. Or, said another way, to increase the current through a given resistance, the voltage must be increased. Further, if you double the voltage applied to a given resistance, the current will double. Simple and easy.

What happens to potential energy at 0 kelvin?
It remains the same. The formula for determining PE is PE = m•g•h, where m is mass in kg, g is 9.8m/s2, and h is height above the ground in meters. Temperature is not a factor in determining potential energy.
What is the cell potential?
Cell potential, also known as electromotive force (EMF), is the measure of the driving force behind the flow of electrons in an electrochemical cell. It is the difference in electric potential between two electrodes in a cell and is a measure of the cell's ability to produce an electric current. The cell potential is a key factor in determining the feasibility and direction of redox reactions in a cell.
How much work is done in moving a charge of 2 C across two points having a potential difference of 12 volt?
The work done in moving a charge across a potential difference is given by the formula: work = charge * potential difference. Therefore, the work done in moving a charge of 2 C across a potential difference of 12 volts is 24 Joules.

What is potencial difference measured in?
The unit of measure is the Volt Potential difference is basically electrical "pressure" (an excess of electrons). Volt.....The unit of electric potential. Named after the Italian physicist Alessandro Volta (1745- 1827). The potential difference is the difference in charge at the poles of a current source The volt (symbol: V) is the SI derived unit of electromotive force, commonly called "voltage". It is also the unit for the related but slightly different quantity electric potential difference (also called "electrostatic potential difference"). ... en.wikipedia.org/wiki/Volt

What is the relationship between the potential difference and the motion of a charged particle in a uniform electric field?
The potential difference in a uniform electric field affects the motion of a charged particle by determining the direction and speed of its movement. The greater the potential difference, the stronger the force on the charged particle, leading to faster motion in the direction of the field.
Energy needed to move 4 coulombs of charge is 4 joules .the potential difference is how much?
The potential difference is 1 volt. This is because potential difference is given by the formula V = W / Q, where V is the potential difference, W is the work done (energy) moving the charge, and Q is the charge. In this case, V = 4 J / 4 C = 1 V.
