2. The needle of a compass changes direction when it is placed near a current-carrying wire. It shows the___effect of electric current. 相关知识点: 试题来源: 解析 1. (a) ammeter (b) Ampere/A 2. magnetic 电流可以用安培计测量,单位是安培(A)。指南针放在通电导线附近会改变方向,这是电流...
On the other hand, electric current is the rate at which electric charge flows through a given area. Current is measured in the unit of Coulombs per second, which is known as an ampere (A). Three basic electrical component parameters are then derived from these two characteristics. A resist...
Ampere: Andre Marie Ampere was a French scientist who lived from 1776 to 1836. Ampere was a physicist who is remembered for discovering electromagnetism, for which he developed mathematical theories to explain the relationship electricity and magnetism. ...
The energy replaces the mass as a fundamental unit in the introduced US as it plays a dominant role in most of the scientific and engineering fields. The ampere is not included as a fundamental unit since the charge is considered as a form of energy that is measured in one of the US ...
Because the mass unitslugis uncommon, the USCS is referred to as the foot-pound-second (fps) system, but strictly speaking, the pound (lb) is a unit of force, not mass. Conversely, in the SI system the mass unit of kilogram is often used to express force (of gravity), as in a ...

What Is an Amp? To put it simply, an amp refers to the unit of electric current in the International System of Units (SI). It is derived from the word "ampere," named after the French physicist André-Marie Ampère, who made significant contributions to the understanding of electromagnetism...
