Inductance is proportional to the cross-sectional area of a coil.

More Questions from Inductors

• In a dc circuit, the only conversion of energy to heat is in the inductance of the coil itself.
• An RL filter could be a high-pass or a low-pass filter.
• The primary and secondary are in phase.
• The secondary current in a transformer depends on the secondary voltage and load resistance values.
• The time constant of an inductive circuit is dependent on the circuit's resistance.
• Inductors are not as versatile as capacitors.
• The output of the secondary winding is 15 V.
• Faraday's law states that the polarity of induced voltage in a coil is in opposition to the current change through that coil.
• An ac generator will produce a constant waveform.
• A magnetic field results whenever a current flows through a conductor.
