Inductance is the property of a device that tells how effectively it induces an emf in another device. Mutual inductance is the effect of two devices in inducing emfs in each other.
Inductors as Circuit Elements. Inductors oppose variations in the current through a circuit. -In DC-circuit, L helps to maintain a steady current (despite fluctuations in applied emf). In AC circuit, L helps to suppress fast variations in current.
obvious example is a motor, whose windings have an inductance. More generally, a device with a current-induced magnetic field that interacts like an inductor will have inductance.
Physically, the inductance L is a measure of an inductor’s “resistance” to the change of current; the larger the value of L, the lower the rate of change of current. Example 11.2 Self-Inductance of a Solenoid Compute the self-inductance of a solenoid withN turns, length l, and radius R with a
This chapter reviews the concepts of resistance, capacitance, and inductance in depth. Even though most electrical and computer engineers have studied and used these concepts for some time, the concepts are often misunderstood. When you are finished with this chapter, you should be able to:
Inductive effect is everywhere! Nearly all electric circuits have currents flowing through conducting wires. Since it’s difficult to shield magnetic fields, inductive effect occurs even we do not purposely add an inductor into the circuit.
The answer is yes, and that physical quantity is inductance. In this chapter, we look at the applications of inductance in electronic devices and how inductors are used in circuits. 14.2: Mutual Inductance. Inductance is the property of a device that tells us how effectively it induces an emf in another device.
