Current Units Introduction
Ampere (A) The basic unit of electric current, representing the amount of charge passing through a conductor's cross-section per second. Specifically, 1 ampere equals 1 coulomb per second (1 A = 1 C/s), and it is one of the seven base units in the International System of Units (SI). Amperes are commonly used to describe the strength of an electric current, such as the current consumption of household appliances and the discharge rate of batteries.
Milliampere (mA) One-thousandth of an ampere, equal to 0.001 amperes (1 mA = 0.001 A). It is commonly used to describe smaller amounts of current, such as in electronic devices and small circuits. Milliamperes are very common in modern electronics, such as the current measurement in smartphones, computers, and other portable devices. The current of electronic components like diodes, resistors, and transistors is often expressed in milliamperes to ensure precise circuit design and analysis.
Kiloampere (kA) One thousand times an ampere, equal to 1,000 amperes (1 kA = 1,000 A). It is used to describe very large amounts of current, typically in industrial applications and high-power electrical systems. For example, the current consumption of welding machines and large electric motors may be measured in kiloamperes. Additionally, in power transmission and distribution systems, especially in high-voltage transmission lines, kiloamperes are a common unit of current used to describe massive current flows.
