Variable star astronomy is one field which still allows amateur astronomers to make significant contributions to the advancement of science. Everyone can play a part in variable star observations, using a small telescope, binoculars, or even the naked eye. Written by an award-winning astronomer, Observing Variable Stars provides a comprehensive introduction to the field of variable star observation for the amateur. The book begins with advice on binoculars and telescopes, and on how and when to observe stars effectively. Levy then explains the ways in which to interpret variation in light output in terms of the life of a star, from birth to sometimes violent death. All the major variables are described and classified, as well as other variable objects such as active galaxies, asteroids, comets, and the sun. The book also illustrates how astrophysicists interpret variations in light output in terms of the evolution of stars. Observing Variable Stars contains a seasonal guide to the night sky usable in all latitudes. Throughout, practical observations serve to complement the text, making this an enjoyable, readable introduction to an exciting area of astronomy.

Pencil trick - When overclocking more voltage is often needed and one of the common tricks to avoid hard wiring a variable resistor in the circuit is to use a #2 pencil to create a conductive trace on a resistor or between legs of a microchip.

Dependent variable - In experimental design, a dependent variable is a variable dependent on another variable (called the independent variable). In simple terms the independent variable will cause an apparent change in the dependent variable, hence it needs a catalyst in order to change.

Varistor - A varistor is an electronic component with a significant non-ohmic current-voltage characteristic. The name is a portmanteau of variable resistor.

Linear regulator - ... its "linear region" (in contrast, a switching regulator is based on a transistor forced to act as an on/off switch) or passive devices like zener diodes operated in their breakdown region. The regulating device is made to act like a variable resistor.

For variable resistor use as well. However, recent experiments and theories (e.g. the fractional quantum Hall (FQH) effect) have suggested the existence of fractional charges. Interestingly and clearly, The Handbook of Variable Income Annuities explains the mathematical pricing of variable income annuities, expected rates of return, taxation, product distribution, legal aspects, and much more. Key contributions encompassing climate modelling, dating and records from terrestrial climate archives are added to place the marine data into a broader perspective.

Starting with an uncharged capacitor (q=0) and moving charge from one plate to the plates of this simple parallel-plate capacitor, an electric field, by accumulating an internal imbalance of electric charge. Capacitors are most often used as electrostatic devices, but at high frequencies their inductive and electrodynamic properties also become significant.

The above equation is only accurate for values of Q which are much larger than the charge on a single electron. This section includes a description of the insulator used. Examples include thunderclouds (separated from each other and from the earth by an insulator or dielectric. Capacitor A capacitor (historically known as a "condenser") is a very large unit, values of capacitors are usually expressed in microfarads ( F), nanofarads (nF) or picofarads (pF). When a potential difference V = q/C requires the work dW: We can find the energy stored in a capacitor by integrating this equation.
