The self-inductance of a coil depends on which of the following factors? (2021)
Step 1: Understand what self-inductance is. It is a property of a coil that determines how much voltage is induced in it when the current changes.
Step 2: Identify the factors that affect self-inductance. These include the number of turns in the coil, the area of the coil's cross-section, and the length of the coil.
Step 3: Realize that more turns in the coil increase self-inductance because it creates a stronger magnetic field.
Step 4: Know that a larger area of cross-section allows more magnetic field lines to pass through, increasing self-inductance.
Step 5: Understand that a longer coil decreases self-inductance because the magnetic field is spread out over a larger distance.
