More Questions from Inductors

• Self-inductance is the property that causes an electromotive force to be produced in a conductor.
• Lenz's law states that the current induced in a circuit due to a change in the magnetic field is so directed as to oppose the change in flux or to exert a mechanical force opposing the motion.
• Kirchhoff's voltage law does not apply to series RL circuits.
• For inductions in series, LT = L1 + L2 + L3 +...
• Inductors connected in series will increase the total inductance value.
• Five time constants are required for current in an inductor to reach a maximum value.
• Magnetic force is the force that produces a magnetic field.
• Maximum power will transfer across a transformer when the primary impedance equals the secondary impedance.
• Inductance is proportional to the cross-sectional area of a coil.
• In a dc circuit, the only conversion of energy to heat is in the inductance of the coil itself.
