কীভাবে Inductance গণনা করবেন
Inductance কি?
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.

সচরাচর জিজ্ঞাসা
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.
