A current–voltage characteristic or I–V curve (current–voltage curve) is a relationship, typically represented as a chart or graph, between the electric current through a circuit, device, or material, and the corresponding voltage, or potential difference, across it.
The exchange current is the current at equilibrium, i.e. the rate at which oxidized and reduced species transfer electrons with the electrode. In other words, the exchange current density is the rate of reaction at the reversible potential (when the overpotential is zero by definition).
A currency pair is the quotation of the relative value of a currency unit against the unit of another currency in the foreign exchange market.The currency that is used as the reference is called the counter currency, quote currency, or currency [1] and the currency that is quoted in relation is called the base currency or transaction currency.
Sterling (ISO code: GBP) is the currency of the United Kingdom and nine of its associated territories. [3] The pound ( sign: £ ) is the main unit of sterling, [ 4 ] [ c ] and the word pound is also used to refer to the British currency generally, [ 7 ] often qualified in international contexts as the British pound or the pound sterling .
Position vectors r and r′ used in the calculation. The starting point is Maxwell's equations in the potential formulation using the Lorenz gauge: =, = where φ(r, t) is the electric potential and A(r, t) is the magnetic vector potential, for an arbitrary source of charge density ρ(r, t) and current density J(r, t), and is the D'Alembert operator.

Angle notation can easily describe leading and lagging current: . [1] In this equation, the value of theta is the important factor for leading and lagging current. As mentioned in the introduction above, leading or lagging current represents a time shift between the current and voltage sine curves, which is represented by the angle by which the curve is ahead or behind of where it would be ...
This ongoing current in both directions is called the exchange current density. When the potential is set more negative than the formal potential, the cathodic current is greater than the anodic current. Written as a reduction, cathodic current is positive. The net current density is the difference between the cathodic and anodic current density.
The current balance in 2013 as a percentage of GDP was 1.6%. Germany for 2013 was 238.61, and 2014 was 285.82 with each quarter between 2013 Q1 through 2015 Q2 ranging from a low of 54.13 in Q3 2013 to a high of 68.89 in Q1 2014. Germany's current account balance in Q2 2015 was up to 68.39. The current balance in Q2 as a percentage of GDP was 8.2%.
