E is a shorter form of EMF, which stands for "ElectroMotive Force", which is a fancy term for Voltage. Technically, voltage is a unit of potential energy. When a conductor is connected between two sources of dissimilar charge, a force is asserted on the electrons in the atoms and molecules in the conductor. This is modeled as a decrease in potential energy and an increase in "kinetic" energy in the form of electron motion, but this is really a simplified model of the actual much more complicated physics behind what is really happening.
False. Voltage (E) is the potential difference, i.e. electrical potential, in joules per coulomb. Current (I), on the other hand, is electrical charge flow, in coulombs per second. The two units are not related except through a common term such as resistance (R). E = IR I = E/R R = E/I
Voltage(E)=Amps(I) x Resistance(R) (ohms) use this formula to solve for other two.
The ratio of voltage to current is called resistance. In hydraulic terms, you can equate voltage to the difference in pressure between two points, current with the resulting flow of fluid between those points , and resistance as the opposition to that flow.
Here is the formula you use. I = E/R. I = amperage, E = volts, R = resistance in ohms.
It stands for electrode. As opposed to R ( rod) for gas welding or TIG welding. If it carries electrical current it is an electrode.
E=IR is Ohm's Law. Electromotive Force equals current times resistance. It is the fundamental equation of electronicalism.

Electromotive force or electromotance measured in volts.Just think of it as volts. Like in Ohm's Law:R=E/I or I=E/R or E=I*RE stands for volts, I stands for current (from the French word intensite'),and R stands for resistance.
Voltage(E)=Amps(I) x Resistance(R) (ohms) use this formula to solve for other two.

Resistance is the opposition to flow or movement.Resistance in a a mechanical system could be friction, wind, gravity.Resistance can be opposition to a policy, or to an invasion (e.g. French Resistance).Resistance in an electrical circuit is the limiting or opposition to current flow. It is measured in Ohms.----Electrical ResistanceThe technical definition is "Electrical resistance is a ratio of the degree to which an object opposes an electric current through it, measured in ohms."In simplfied terms, electrical resistance is broadly equivalent to friction in a mechanical system. If you applied a voltage to a circuit with zero resistance then you would get an infinite current. In reality all circuits have some resistance which limits the current.We can predict the current in a given circuit using Ohms law:V = I x RWhere:V is Voltage (measured in Volts)I is current (measured in Amps)R is resistance (measured in Ohms)You will often see this in the form E = I x R. It is exactly the same thing, just a different convention where "E" is used for voltage instead of "V"Ohms law is:V=I/RV=Voltage (volts)I=Current (amps)R=Resistance (Ohms)Resistance in an AC circuit is called Impedance (Z)Electrical resistance is the amount that an object opposes electrical current. All things being equal (temperature, purity, etc.), resistance is a function of both its physical geometry and the resistivity of the material it is made from. Impurities in materials and fluctuation of temperature can effect the amount of resistance a material will exhibit.----------Electrical resistance is the amount that an object opposes electrical current. All things being equal (temperature, purity, etc.), resistance is a function of both its physical geometry and the resistivity of the material it is made from. Impurities in materials and fluctuation of temperature can effect the amount of resistance a material will exhibit.There are many different types of resistance, and I recommend that for starters you read up on the Wikipedia article on electrical resistance.http://en.wikipedia.org/wiki/Electrical_resistance
In the formula E=IR, E represents voltage (in volts), I represents current (in amperes), and R represents resistance (in ohms). This formula is known as Ohm's Law in electrical engineering.
