What does it mean for reactive power to be delivered / consumed?
Reactive power in VAR (Volt Amps Reactive) (Q) is power that circulates between the source and the load. Power that is stored in capacitors or inductors. But it is needed. For example, inductive reactive power in …
How do Capacitors and Inductors Add/Remove VARS in AC?
To my understanding, capacitors cause the current to lead the voltage which adds VARS to the circuit and inductors cause the current to lag behind the voltage which removes VARS (in AC circuits). Also, it is my understanding that VARS increase voltage. I work for one of the largest utilities...
Tuning Capacitor
A tuning capacitor is a variable capacitor used in an electronic circuit of a radio, and usually connects in parallel to a loop antenna to form a parallel tuned circuit. There are many uses and applications for a variable capacitor; the most typical use being in an AM/FM radio circuit. If you were building a crystal radio, then you will most definitely need this …

B8: Capacitors, Dielectrics, and Energy in Capacitors
In this derivation, a lower case (q) represents the variable amount of charge on the capacitor plate (it increases as we charge the capacitor), and an upper case (Q) represents the final amount of charge. Similarly, a lower case (v) represents the variable amount of voltage across the capacitor (it too increases as we charge the …
Variable and Trimmer Capacitors Explained
For example, PTFE exhibits a higher dielectric constant than air (which is equal to unity) and can support trimmer capacitors with a much higher DWV rating, on the order of 15,000V or more. Trimmer capacitors based on ceramic dielectrics are small, inexpensive, and readily available on tape and reel for use with automated manufacturing …

8.2: Capacitance and Capacitors
A variable capacitor used for tuning radios is shown in Figure 8.2.5 . One set of plates is fixed to the frame while an intersecting set of plates is affixed to a shaft. Rotating the shaft changes the amount of plate area that overlaps, and thus changes the capacitance. Figure 8.2.5 : A variable capacitor.
