Difference Between Ampere and Coulomb

关键区别 - 安培vs库仑

Ampere and Coulomb are two measurement units that are used to measure thecurrent。电流conductor以安培,而库仑量ure the amount ofcharge。One ampere is equal to the flow of one coulomb of a charge in a second. Unlikecoulomb,which测量充电量。这是安培和库仑之间的关键区别。

当导体内部的电流载体在A的效果下移动时，电流发生在导体内部。电压区别。电流如何发生的一个非常普遍的例子是流过管道的水。如果管道保持水平，则内部不会流动。如果至少稍微倾斜，它将在两端之间产生潜在的差异，并且水将开始流过管道。斜率越高，电势差越高，因此，每秒的水流量越高。同样，如果导线的两端之间的电压差较高，则电荷流量的量将更高，从而使高电流变得更高。

What is Ampere?

The measuring unit of current, Ampere, is named after a French mathematician and physicist André-Marie Ampère who is considered as the father of electrodynamics. Amperes are also called as安培， 简而言之。

安培力法指出两条携带电流的平行电线相互施加力。国际Unites（SI）根据该安培的力量定义了一个安培；“安培是那个恒定电流，如果将其保持在两个无限长度的直接平行导体中，可忽略不计的圆形横截面，并在真空中分开一米，将在这些导体之间产生等于2×10-7 Newtons的力每米长度”。

根据欧姆定律，电流与电压有关：

V = I x R

R is the resistance of the current carrying conductor. The power P consumed by a load relates to the current flows through it and the supplied voltage according to:

P = V x I

This can be used to understand the quantity of an ampere. Consider an electric iron having 1000 W rating, which is connected to the power line of 230 V. The amount of current it consumes to heat up can be calculated as:

P = VI
1000 W = 230 V ×I
I = 1000/230
I = 4.37 A

与此相比，在电弧线焊接中，使用近1000 a的电流光束用于熔化铁杆。如果考虑闪电，平均闪电闪光灯传递的电流约为10,000安培。但是，还测量了100,000安培的闪电闪光灯。

Current is measured usingAmmeter。Ammeter works in different techniques. In a moving-coil ammeter, a coil mounted along the coil’s diameter is supplied with the measured current. The coil is placed between two magnetic poles; N and S. As per Flemming’s Left-Hand Rule, a force is induced on a current carrying conductor which is placed inmagnetic field。因此，安装线圈上的力将线圈围绕其直径旋转。这里的偏转量与线圈与电流成正比；因此，可以进行测量。但是，这种方法需要打破导体并将其放置在中间。由于这不能在运行系统中完成，因此在夹具仪中使用磁方法来测量AC and DC currentswithout a physical contact with the conductor.

What is Coulomb?

The SI unit Coulomb, which is used to measure electric charges, is named after the physicist Charles-Augustin de Coulomb who introduced Coulomb’s law.库仑定律states that when two chargesq₁和q₂are placedr距离分开，一支部队根据：

f =（k_eq₁q₂)/r

Here,k_eis Coulomb’s constant. A Coulomb (C) is equal to the charge of roughly 6.241509×10¹⁸number of electrons or protons. Hence, the charge of a single electron can be calculated as 1.602177×10^-19C.使用电表测量静电电荷。就像上一个电铁的示例一样，可以在一秒钟内传递到铁中的电荷量为：

I = Q/t
Q = 4.37 A ×1 s
Q = 4.37 C

在闪电闪烁期间，大约15个库罗姆斯电荷可能会以30,000 a的电流从一秒钟的一秒钟内从云中扎根。但是，雷云可以在闪电期间容纳数百个库洛姆斯电荷。

Charge is also measured in ampere-hours (Ah = A x h) in batteries. A typical mobile phone battery of 1500 mAh (theoretically) holds 1.5 A x 3600s = 5400 C of charge, and to make a sense of the charge, it is expressed as the battery can provide 1500 mA current within an hour.

Ammeter is used to measure the current.	Charge is measured using Electrometers.
Definition
Current is defined by SI with Ampere’s force law, considering the force acting on current carrying conductors.	库仑正式定义为将电荷与电流相关联的安培秒。

Summery – Ampere vs Coulomb

与库仑不同，安培用于测量电荷的流动，该电荷用于测量静电电荷。尽管Ampere与库仑有关，但根据定义，安培是在不使用电荷的情况下定义的，而是使用作用于电流导体的力。这是安培和库仑之间的区别。
