百度试题 题目Electric current (i) is the time rate of charge (q), measured in amperes. Given by the Eq. , t is from 0 to 1 seconds, i = ( ) A A.0B.0.5C.1D.1.5相关知识点: 试题来源: 解析 C
The unit of electric current is the ampere; 1 amp is the flow of 1 coulomb of charge per second. Electrical resistance is the extent to which a material resists the flow of electric current, and is measured in ohms. Metals such as silver and copper have low resistance, allowing current ...
Passing a current through a light source, such as light emitting diodes (1), and therefore the spectrum of the polychromatic light emitted from the light source distribution depends on the size of the light source by the current i, and thus can determine the value of the current i. 一个...
aElectric current can be directly measured with a galvanometer, but this method involves breaking the electrical circuit, which is sometimes inconvenient 电流可以用电流计直接地测量,但这个方法介入打破电路,是有时不便的[translate]
The SI unit of current is ampere (Unit Symbol=A). Formula: 1 Ampere = 1 Coulomb of charge passing a given point per second. Read:How is Electricity Generated, Transmitted and Distributed? How is Electric Current Measured? Electric current is measured using anAmmeter. Milliammeters are used ...
Electric current is measured using a device called an ammeter. There are various types of ammeters available. It is connected in series to the circuit such that full current flows through its coil. For the measurement of high alternating currents, current transformers are used and the ammeter is...
