Dive into the relationship between capacitors and inductors. Learn how capacitors and inductors can be used to build RC and RL filters with a similar frequency response, but the way they remove unwanted signal energy is very different.
- [Instructor] Since capacitors…and inductors are both reactive components…that store energy and oppose change,…there are times when a circuit can be designed…to use one or the other to do the same thing.…However, capacitors and inductors…are not direct replacements for each other…because they work in very different ways.…For starters, the way that capacitors and inductors…store their energy is different.…Capacitors store energy in the electric field…that exists between two charged plates.…
Inductors, on the other hand, store energy…in the magnetic field surrounding a coil of wire.…In regards to how capacitors and inductors react…to change, capacitors resist sudden changes…in voltage by absorbing and releasing stored charge,…attempting to maintain a constant voltage…across the capacitor.…Inductors resist change in current…by expanding and collapsing the magnetic field…in the coils.…And they attempt to maintain a constant current…through the inductor.…The way that capacitors and resistors…respond to different frequencies is also different.…
