Frequently Asked Questions
What is the relationship between Henrys, Millihenrys, and Microhenrys?
Inductance metric prefixes scale by factors of 1,000. One Henry (H) equals 1,000 Millihenrys (mH), and one Millihenry equals 1,000 Microhenrys (μH). Consequently, one Henry equals 1,000,000 Microhenrys.
How does an inductor store electrical energy?
An inductor stores energy in the magnetic field created by electric current flowing through its coils. The stored energy equals E = 0.5 × L × I², where L is inductance in henrys and I is current in amperes.
What happens when you connect inductors in series or parallel?
In series (without mutual coupling), total inductance is the direct sum (L = L1 + L2). In parallel, reciprocal values sum (1/L = 1/L1 + 1/L2), resulting in a lower equivalent inductance.
