It is abbreviated E in the international metric system but also, popularly, as emf. Despite its name, electromotive force is not actually a force. It is commonly measured in units of volts, equivalent in the metre–kilogram–second system to one joule per coulomb of electric charge.What...
In what units is resistance measured? What is the SI unit for reactance? What is a warm air current called? What country is Aconcagua located in? What is the unit for electrical energy? What is an electric field line? What does AC stand for in electricity?
a因为我的听说能力比较弱 Because I heard ability quite is weak[translate] a你当时看的是这个形状的 You at that time looked were this shape[translate] apointed to by s1 指向由s1[translate] a电势是相对而言的,就跟重力势能一样,没有参照物是没法说出它的势能是多少。 同理不选取一个零电势点,是...
What is the dimensional formula for strain? What are the laws of resistance? What is Electromagnetism? What is the electromotive force? Name the physical quantity which is measured in terms of Horsepower. what is the power if it takes 11s to drag the sled 80m?
27 The electromotive force ( e.m. f.) of a rechargeable battery is 6.0 V.What does this mean? C A 6.0 J is the maximum energy the battery can provide in 1.0s. B 6.0J is the total energy the battery can provide before it has to be recharged. C 6.0J of energy is provided by ...
In brief, voltage = pressure, and it is measured in volts (V). The term recognizes Italian physicist Alessandro Volta (1745-1827), inventor of the voltaic pile—the forerunner of today's household battery. In electricity's early days, voltage was known as electromotive force (emf). This is...
Current (I) is a rate of flow and is measured in amps (A). Ohms (R) is a measure of resistance and is analogous to the water pipe size. Current is proportional to the diameter of the pipe or the amount of water flowing at that pressure. ...
The ability of inductors to resist the current is proportional to an inherent property known as inductance. This is denoted by L, which honors Emil Lenz, a Russian physicist and it is measured in H (henries), which is also named after Joseph Henry, the American scientist. Inductors can onl...
The emf of the following cell was measured at 25{eq}^\circ {/eq}C and found to be 0.322 V. What is the pH of the solution? $$Pt/H_2(g)/HCl( ?\ M,\ aq)/ AgCl(s)/Ag $$ Nernst Equation: Each electrochemical (re...
The voltage between two points in a system can be measured by using avoltmeter. To measure a voltage, a voltmeter must be connected in parallel with the component whose voltage is to be measured. One lead of the voltmeter must be connected to the first point and one to the second point....
