Mathematical Relationships
1 Henry (H) = 1,000 millihenries (mH)
1 mH = 1,000 microhenries (μH)
1 μH = 1,000 nanohenries (nH)
1 nH = 1,000 picohenries (pH)
Scientific Notation
- • 1 H = 10³ mH = 10⁶ μH = 10⁹ nH = 10¹² pH
- • 1 mH = 10⁻³ H = 10³ μH = 10⁶ nH = 10⁹ pH
- • 1 μH = 10⁻⁶ H = 10⁻³ mH = 10³ nH = 10⁶ pH
Conversion Examples
- • 2.5 H = 2,500 mH = 2,500,000 μH
- • 470 μH = 0.47 mH = 0.00047 H
- • 100 nH = 0.1 μH = 0.0001 mH
Understanding Electrical Inductance
Fundamental Concepts
- • Definition: Property of electrical conductor to oppose changes in current
- • Unit: Henry (H), named after Joseph Henry
- • Symbol: L (from "Lenz's law")
- • Formula: L = Φ/I (flux linkage per unit current)
Types of Inductors
- • Air Core: No magnetic core material
- • Iron Core: High inductance, power applications
- • Ferrite Core: High frequency applications
- • Toroidal: Minimal electromagnetic interference
AC vs DC Behavior
- • DC: Acts as short circuit (steady state)
- • AC: Reactance XL = 2πfL
- • Energy Storage: E = ½LI²
