Why do capacitors and inductors store energy but resistors do …
A magnetic field with which energy can be stored can also act in inductors. Where, as if we encounter resistance, we can only have a power loss because it is opposite to the current. You may also find that AC capacitors and inductors offer imaginary resistance, i.e. an impedance that does not generate power loss, but refers to stored …

6.1.2: Capacitance and Capacitors
Q is the charge in coulombs, V is the voltage in volts. From Equation 6.1.2.2 we can see that, for any given voltage, the greater the capacitance, the greater the amount of charge that can be stored. We can also see that, given a certain size capacitor, the greater the voltage, the greater the charge that is stored.

Inductor and Capacitor Basics | Energy Storage Devices
Ideal capacitors and inductors can store energy indefinitely; however, in practice, discrete capacitors and inductors exhibit "leakage," which typically results in a gradual reduction in the stored energy over time.
How do inductors store energy?
2. If you want to store energy in an inductor you run current trough it and then you short the inductor. The energy will be stored in the magnetic field and the current will keep flowing, at least for a while. Unlike with many capacitors this is only a short term storage (it works well for μs μ s to ms m s, which is used in switching mode ...
How does an inductor store energy?
The electrons lose energy in the resistor and begin to slow down. As they do so, the magnetic field begins to collapse. This again creates an electric field in the inductor, but this time it pushes on the …
How does an inductor store energy?
An Inductor stores magnetic energy in the form of a magnetic field. It converts electrical energy into magnetic energy which is stored within its magnetic field. It is composed of a wire that is coiled …
Beginner''s Corner: Inductors in DC Circuits
Boost Converters, which are used to increase a DC voltage, say from a 9V battery at the input to the 100V or more needed to drive a vacuum fluorescent display, use an inductor''s ability to store and return energy to "boost" the voltage. In fact, older CRT-based monitors and TVs used a flyback circuit (based on a set of coils) to generate ...
Inductor vs a capacitor
A capacitor and an inductor are similar in the way that a capacitor resists a change of a voltage and an inductor resists a change in current. The "strength" of their resistance depends on their value. Capacitors are widely used to clean up a power supply line, i.e. remove noise or ripple at (higher) frequencies.
Inductor
The dual of the inductor is the capacitor, which stores energy in an electric field rather than a magnetic field. Its current–voltage relation is obtained by exchanging current and voltage in the inductor equations …
Inductor vs. Capacitor: What Is the Difference? | Solid State Inc.

Real-world circuit elements (article) | Khan Academy
DC line loss is an example of a parasitic effect, When DC voltage is carried over a long distance it can lose voltage. If you had a DC power supply with +20V at the voltage source, and measured the voltage at the end of a 75 foot wire, It may show +19.5V. While marginal, it is a very real world example.

The Inductor and the Effects of Inductance on a Coil
An ideal inductor is classed as loss less, meaning that it can store energy indefinitely as no energy is lost. However, real inductors will always have some resistance associated with the windings of the coil and whenever current flows through a resistance energy is lost in the form of heat due to Ohms Law, ( P = I 2 R ) regardless of whether the current is …

How Inductors Work | HowStuffWorks
Once the field is built, current can flow normally through the wire. When the switch gets opened, the magnetic field around the coil keeps current flowing in the coil until the field collapses. This current keeps the bulb lit for a period of time even though the switch is open. In other words, an inductor can store energy in its magnetic field ...
Fundamentally knowing when to use capacitors / inductors
If we need to block DC we use a capacitor. If we need to block very high frequency AC we use an inductor. If we need to design a filter we (can) use resistors, capacitors and inductors (and op-amps and transistors etc..) If we need to design a switch mode power supply we use capacitors and inductors and diodes.
