Capacitor circuits with light bulb
When one places a capacitor in a circuit containing a light bulb and a battery, the capacitor will initially charge up, and as this charging up is happening, there will be a nonzero current in the circuit, so the light bulb will light up. However, the capacitor will eventually be fully charged at which point the potential between its plates

CAPACITORS AND FANS WITHIN UPS SYSTEMS
The lifespan of capacitors and fans are subject to change if environmental conditions (premises, load type, usage) are abnormal or harsh for the equipment. When a capacitor fails visible effects are often not seen however, the other capacitors will have to undertake the extra workload, which in turn shortens their useful lives.
People in the UK using smart switches with no neutral wire
The switch I bought came with a capacitor which I installed so no flickering happens, but it makes quite a disturbing buzzing/flickering noise whenever the light is on. For anyone with experience in this matter, Is this the case of needing a better quality capacitor, needing a more compatible light bulb, light switch or did injust install the capacitor wrong?

In practice this is more important than the resistive load, since the limited drive current of an output has to charge/discharge one or more of these capacitors. In high-speed systems, if there are many of them connected to an output
Problem with Lutron Switches | Information by Electrical
The switches probably have a triac instead of a mechanical relay. Triac''s leak some voltage when there is no load to shunt it. The reason CFLs blink when off is the switch leaks enough current to charge up the cap in the CFL ballast circuit and when it reaches enough voltage the light blinks which discharges the cap and restarts the cycle.

A must-have for electronic engineers: An in-depth look at capacitive loads
The working principle of capacitive load: the capacitor is connected to the power supply, and the charge is stored on the capacitor plate to form an electric field. When the power supply voltage changes, the capacitor responds, releasing or absorbing charge, changing the waveforms of current and voltage, creating a capacitive load.

Connecting a capacitor across that load can help to shunt some of the switch current, decreasing the current flowing in the load, and helping to avoid the unwanted operation.

6 FAQs about [What is a light load capacitor]
What are the different types of capacitor loads?
Types of Capacitive Loads Capacitive loads store electrical energy in a capacitor and release it back into the circuit. Unlike resistive loads or inductive loads, CLs have the characteristic of the current reaching its peak before the voltage does.
What is a useful capacitive load?
A useful capacitive load is, for example, the capacitor in an RC integrating circuit. In this case, its slow charging is something we want, because it allows us to get an idea of the time through the voltage (hence the resistor in series to the capacitor). In this way, we can make timers (555), ramp generators and more.
Why do we add a capacitor to each lamp?
Adding a capacitor to each lamp corrects the power factor bringing it back close to unity (1.0). This solves the problem of associated voltage drop and also, for large energy users, eliminates power factor surcharge on the bills - for that part of the load at least.
Is a capacitive load useful or harmful?
Like anything in this world, capacitive load can be both useful and harmful: A useful capacitive load is, for example, the capacitor in an RC integrating circuit. In this case, its slow charging is something we want, because it allows us to get an idea of the time through the voltage (hence the resistor in series to the capacitor).
Why does a capacitive load have a leading power factor?
In capacitive load, Current leads voltage by 90 degrees. Hence it has a leading power factor. Since the capacitor blocks DC current and allows AC to pass through it, the capacitive load shows very high resistance for DC supply and low resistance for AC.
Is capacitor bank a capacitive load?
Negative 2300 VAR or 2.3 KVAR. So, this negative reading indicates that, the power is actually flowing from capacitor bank to the generator. /And hence, we cannot call capacitor bank as capacitive load. Basically, there is no such thing which you can classify as capacitive load. So, that is all about the types of electrical load.
