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 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
A battery has a difference in potential energy between the positive terminal and negative terminal which units express the difference?
Volts. Volts is another term for potential.
What is a difference in electric charge called?
The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
What is the formula of ilkovic equation in the diffusion current?
ilkovic equation gives us the chance to know what is the potential difference of any system.the potential difference can easily be calculated with the help of Hg-drop!there is an equation with the help of which we can know very other things except the potential difference!

How would you explain the difference between potential and kinetic energy?
Kinetic energy is energy related to movement. The formula is (1/2) mass times velocity squared. Potential energy is energy of position. The formula for gravitional potential energy is mgh (mass times gravitation times height).
What is the formula for the statement of Ohm's Law?
v=iR (v=potential difference two pts, R=resistance)
Is there a formula for determining degrees for an acute angle?
There isn't a formula for determining the degrees of a simple acute angle. The only way is with a protractor or estimate.
How much electrical energy is required to move 4.00 mC of charge through a potential difference of 36.0 V?
0.144 JOULES. One can calculate this from the formula E=Vq in which E is energy, V is potential difference & q is charge.
What variable represents potential difference?
The variable that represents potential difference is V, which stands for voltage.
How much energy is expended in moving a 20 coulomb charge through a potential difference of 0.5 volts?
To calculate the energy expended in moving a charge through a potential difference, you can use the formula: Energy (E) = Charge (Q) × Potential Difference (V) Given: Charge (Q) = 20 Coulombs Potential Difference (V) = 0.5 Volts Plugging in the values: E = 20 C × 0.5 V E = 10 Joules Therefore, the energy expended in moving a 20 Coulomb charge through a potential difference of 0.5 Volts is 10 Joules.
