The unit of inductance is an expression of the ratio between the rate of current buildup and the voltage across an inductor. An inductance of 1 henry (1 H) represents a potential difference of 1 volt (1 V) across an inductor within which the current is changing at the rate of 1 ampere per second (1 A/s). Henry is a huge unit of inductance.
Unit of Inductance [Click Here for Previous Year Questions] The sign "L" is commonly used to represent an inductor on a circuit diagram or in an equation. Inductors are usually labeled L 1, L 2, etc. on circuit diagrams. The henry, H, is the SI unit of inductance, which can be expressed in terms of current and voltage rate of change.
This process is known as self-inductance. We actually define self-inductance in the same way that we defined mutual inductance – the ratio of the total flux through the N N coils to the current that supplies the magnetic field. Naturally the units are therefore the same as mutual inductance. L ≡ NΦ I (5.3.7) (5.3.7) L ≡ N Φ I.
Jun 28, 2024 · The unit of magnetic inductance is the henry, named in honour of the 19th-century American physicist Joseph Henry, who first recognized the phenomenon of self-induction. One henry is equivalent to one volt divided by one ampere per second.
Example 11.4 Mutual Inductance of a Coil Wrapped Around a Solenoid. long solenoid with length l and a cross-sectional area A consists of N1 turns of wire. An insulated coil of N2 turns is wrapped around it, as shown in Figure 11.2.4. Calculate the mutual inductance passes through the outer coil.
May 22, 2023 · The unit of mutual inductance is the same as for self-inductance, namely, henry. Two coils have a mutual inductance of 1 H if an emf of 1 V is induced in one coil when the current in the other coil varies uniformly at the rate of 1 A/sec .
The SI unit of inductance is Henry (H). An electric circuit is said to have an inductance of 1 Henry when the current is changed at a rate of one ampere per second and this changing current produces a voltage of 1 volt in the circuit. Henry is a derived unit that is based on 7 base SI units. The SI unit of inductance is Henry whereas the MKS ...
