The meaning of POTENTIAL DIFFERENCE is the difference in potential between two points that represents the work involved or the energy released in the transfer of a unit quantity of electricity from one point to the other.
Janhunen, Difference in the current - voltage relation- ships between dawn and duskside inverted-V events, J. Geophys. Res., 105, 5373 - 5380, 2000b.Olsson, A. and Janhunen, P.: Difference in the current-voltage rela- tionships between dawn and duskside inverted-V events, J. Geo- ...
In general, there is a measurable difference in potential between the two electrodes whether the cell is passing a current or not. 通常,无论电池有无电流流过,两电极之间均具有可测量的电势差。 www.kuenglish.info 2. But she also saw the difference in potential wind energy on an intact mountain...
When a current flows through apotential difference, a quantity of energy is dissipated in the form of heat. This is used to define the unit of potential difference as follows. One volt (1V) is the difference of electric potential between two points of a conducting wire carrying a constant ...

between two points. A movement or a flow ofelectric chargesunder the effect of the potential difference is known as an electric current. The key difference between current and voltage is thata current always involves a movement of electric charges under an electric field whereas voltage does ...
Calculate the change in potential energy when one calcium ion (Ca2+) flows into a muscle cell that has an electric potential difference of -90 mV. Answer in units of J. (charge of an electron is equal to: -1.6e-19C) What is the relationship between current, resistance, and voltage dif...
Key Difference - Potential vs Performance Potential and performance are two words that often go together although there is a key difference between these
解析 A。“potential difference”电势差是驱动电流的力。选项 B“the rate of flow of electric charge”是电荷的流动速率;选项 C“the opposition to the flow of electric current”是对电流的阻碍;选项 D“the electrical energy stored in a conductor”是导体中储存的电能。
The potential difference in a circuit is what causes current to flow through the circuit. The larger the potential difference, the faster the current will flow and the higher the current. The potential difference is the measure of the difference in voltage between two distinct points in a closed...
