Electrolytic
* Some electrolytics have better designs than others.
* can take a temporary overstress for a short while, like heater warm up time.

Electrolytic capacitor
* Most electrolytic capacitors are aluminum electrolytics.
* are capacitors
  - relatively poor noise filters, and also have a short life
  - suitable for use on printed circuit boards
* have a finite lifetime, usually about ten years
  - positive and a negative side
  - tendency to increase in ESR over time due to drying out or corrosion
  - useful life of about ten years
  - several undesirable properties
  - very high voltage capacity and high storage capacity
* use a conducting surface inside a liquid electrolyte
  - special technique to achieve a plate spacing which is very small
+ Capacitor, Electrolytic capacitors: Electronic components
  * Electrolytic capacitors use a conducting surface inside a liquid electrolyte. They have polarity and so they have to be attached correctly. This means one lead is 'positive' and one is 'negative'. The rating of an electrolytic capacitor is easy to find because they are printed with capacitance and voltage rating.

Variable capacitor
* consist of two interleaved sets of metal plates, one set fixed and one movable.
* is made by power diode.

Condenser
* Some condensers use water to cool the refrigerant rather than air.
* are apparatus
  - automotive products
  - coils
  - electrical components
  - lenses
  - of various types
  - part of stills
* change the steam back into water so it can be cycled back to the steam generator.
* is an electrical device
  - older word for capacitor
* uses all copper tubes and fins to resist corrosion due to humidity and cleaning chemicals.

Control panel
* Some control panels are panel assemblies that incorporate electrical switching functions.
* are devices
  - electrical devices
  - located in space shuttles

Electric battery
* Electric batteries supply power underwater.
* is an electrical device

Electric circuit
* Most electric circuits convert electrical energy
* Most electric circuits have bulbs
  - paths
  - involve motors
  - use a combination of series and parallel arrangements
* Some electric circuits consist of batteries.
* abound in today's world.
* are present in several applications
  - used to distribute energy quickly and conveniently to distant locations
  - what make the heart beat but too many circuit make it beat wildly
* behave in the same way.
* can be series or parallel
  - contain parts such as switches, transformers, resistors and transformers
* contain currents that flow in agreement with particular laws.
* is an electrical device

Electrical circuit
* Every electrical circuit has some type of noise in it
  - to contain at least one ground object
* Most electrical circuits involve active components
* are all about energy
  - connected in series or in parallel
  - the most noted examples non-mechanical oscillatory behavior
  - used for all kinds of applications, from blenders to hair dryers to cars
* have fuses that blow.
* provide a means of transferring electrical energy when heat.
* require a complete loop through which the electrical current can pass.

Electrostatic precipitator
* are the most efficient method for removing submicron particles.
* can generate ozone.
* draw in air with a fan.
* have high voltage attract particles
  - the disadvantage of producing some ozone, a known pollutant
* take advantage of the electrical principle that opposites attract.
* use electrostatic forces to separate dust particles from exhaust gases.
