The previous parts are consistent with the behavior of inductors discussed in the text.
Step 1: Plug voltage, resistance, and inductance into the equation I=VR(1−e−RtL) I = V R ( 1 − e − R t L ) and simplify.
An inductor, also called a coil, choke, or reactor is a passive two-terminal electrical component that stores energy in a magnetic field when an electric current passes through it. An inductor usually consists of an insulated wire wound into a coil. When the current passing through the coil changes, the time-varying magnetic field induces an electromotive force (emf) (voltage) in the conductor, described by Faraday's law of induction. According to Lenz's law, an induced voltage has a polarity (direction) that is opposite to the change in current that created it. As a result, inductors prevent any changes in the current passing through them.
An inductor is characterized by its inductance, which is the ratio of voltage to the rate of change of current. In the International System of Units (SI), the unit of inductance is the henry (H), named after the 19th-century American scientist Joseph Henry. It is equivalent when measuring magnetic circuits. Inductors have values that typically range from 1 µH (10−6 H) to 20 H. Many inductors have a magnetic core made of iron or ferrite inside the coil that serves to increase the magnetic field and thus the inductance. Along with capacitors and resistors, inductors are one of the three passive linear circuit elements that make up electronic circuits. Inductors are widely used in alternating current (AC) electronic equipment, especially in radio equipment
