This web page allows you to convert the different electrical inductance units and answers the following questions in particular: What is the history of different units of electrical inductance? What are the uses and applications of different units of electrical inductance? What are some interesting facts about different units of electrical inductance? What are some examples of record values in different units of electrical inductance? How can different units of electrical inductance be converted?
The concept of electrical inductance is one of the most important in electrical engineering, first proposed by the physicist Heinrich Lenz in 1834 who proposed the induction law. However, the term inductance was not used until the late 19th century. Many different units of electrical inductance have been used in the past. In the early 20th century, the unit of electrical inductance was based on the megahenry (MH) and the abhenry (AH). Later, the henry (H) was adopted as the standard unit for inductance and is still being used today.
Different units of electrical inductance are used for different applications. The main use is to measure the inductance of a circuit. The henry is often used for low inductance circuits, while millihenry (mH) to kilohenry (kH) or even higher units are used for higher inductance. The electrical inductance unit is also used in radio-frequency transistors, motors, and generators.
The henry is the most commonly used unit of electrical inductance and is named after the physicist Joseph Henry who first studied the concept of inductance. The millihenry is one thousandth of a henry, the microhenry is one millionth of a henry and the nanohenry is one billionth of a henry. It takes over 300 kilometers of copper wire to make 1 henry of inductance.
Below is a list of some reference or record values in different units of electrical inductance.
To convert different units of electrical inductance, one needs to know the following two equations: inductance (L) is equal to current (I) divided by the rate of change of the magnetic flux density in henry (H), or L = I/dΦ/dt. And 1 henry is equal to 1,000 mH, 1,000,000 µH, 1,000,000,000 nH and 1,000,000,000,000 pH. Having these two equations, you can easily convert any one of the above listed units of electrical inductance to another.
