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.

USD/JPY exchange rate 1971–2023. The yen (Japanese: 円, symbol: ¥; code: JPY) is the official currency of Japan.It is the third-most traded currency in the foreign exchange market, after the United States dollar and the euro. [2]
In electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section. [1] The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the positive charges at this point.
This is a list of tables showing the historical timeline of the exchange rate for the Indian rupee (INR) against the special drawing rights unit (SDR), United States dollar (USD), pound sterling (GBP), Deutsche mark (DM), euro (EUR) and Japanese yen (JPY). The rupee was worth one shilling and sixpence in sterling in 1947.
The Tafel equation describes the dependence of current for an electrolytic process to overpotential. The exchange current density is the current in the absence of net electrolysis and at zero overpotential. The exchange current can be thought of as a background current to which the net current observed at various overpotentials is normalized.
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 ...
The Pakistani rupee (ISO code: PKR) is the official currency in the Islamic Republic of Pakistan. The issuance of the currency is controlled by the State Bank of Pakistan . It was officially adopted by the Government of Pakistan in 1949.
