Paano Kalkulahin si Inductance
Ano ang Inductance?
Inductance measures a conductor's or coil's ability to generate a magnetic field and store energy magnetically. It quantifies the opposition to changing electrical current.
Pormula
The calculator applies L = μ × N² × A / l where μ is permeability
- L
- μ × N² × A / l where μ is permeability — μ × N² × A / l where μ is permeability
- A
- A value — Variable used in the calculation

Mga Karaniwang Mali na Dapat Iwasan
- ✕Neglecting to square the number of turns
- ✕Using inconsistent units for coil dimensions
Mga madalas itanong
Why does inductance increase with the square of turns?
Each additional turn strengthens the magnetic field and increases flux linkage exponentially.
What's the difference between self and mutual inductance?
Self-inductance opposes current changes in the same circuit, while mutual inductance occurs when one coil induces voltage in another.
