Understanding Inductors: Principles, Working, and Applications
Inductors resist changes in current, so if there is a switch that closes and the voltage across an inductor changes from 0V, the voltage will try to change instantaneously but the current through it will take some time to ramp up to its steady state current. As current is a result of a voltage, this causes some strange effects on the voltage.

Capacitors 101: What Do Capacitors Store in Electronic Circuits?
Capacitor Voltage. The capacitor''s working voltage (WV DC) is the maximum amount of voltage that can be applied to the capacitor without damaging the dielectric. Capacitors have a maximum DC voltage. The maximum energy that can be stored safely in a capacitor is limited by the breakdown voltage.
How does a capacitor smooth energy?
Yes, it works basically the same way. However, a capacitor typically has a lower capacity than, say, a battery. When you connect a load to a capacitor, its charge and voltage will decrease over time. That''s why it''s called smooth. A battery does that in the exact same way but much, much slower, because of the higher capacity.

Decoupling Capacitors: Functions, Types, and Best Practices
2 · Voltage Stabilization. Decoupling capacitors are like small energy reservoirs, storing and releasing charge to stabilize voltage levels. When a circuit experiences sudden demand for power, the decoupling capacitor can quickly release its stored energy, preventing voltage dips that might otherwise disrupt sensitive components.
Bypass Capacitor and Coupling Capacitor: Stabilizing Voltage
Thin traces are routed to the bypass capacitor. The current flowing into the voltage converter also does not flow directly from the bypass capacitor. The bypass capacitor is only connected with additional thin contacts. This increases the parasitic inductance of the capacitor and reduces the effectiveness of this component.
