Ch14: Induction and RL Circuits Ch14: Induction and RL Circuits Why an IT graduate should know this . . . - It is esoteric . Join the group . . . . - Inductance, capacitance, and resistance (either separately or in combination) represent the reasons why a wide variety of electrical and electronic circuits behave as they do . . . .
. . . It is necessary to know everything about - inductors - induction - inductance before one can know anything about them . . . And, after (if) one gets a “handle” on inductors, capacitors are easy . . . Ch14: Induction and RL Circuits Ch14: Induction and RL Circuits
