Simple yet effective, capacitors come in a dizzying array of forms and materials, vital to so many circuits for storage, timing, and filtration - the mighty capacitor!
Nicad batteries often die in such a way that they won't take a charge and have zero voltage. This usually means they're shorted out by crystal dendrite growth. Here's a method of bringing them back to life by zapping those shorted crystal dendrites away with too much current and/or voltage. We'll use a welder as a power source. You could also use a car battery, a DC powersupply, or almost anything with some voltage. Charged-up capacitors are popular for this because you can get a very fast pu...

Casein is a protein that is found in milk. Groups of casein normally float around in milk without bonding. These groupings have a negative charge. The acidity of the Red Bull causes the negative charges on the casein groupings to become neutralized. Instead of pushing each other apart, the casein starts to clump together causing the milk to curdle and form solid matter.
There are plenty of times when we need to charge our phones but don't have access to electricity. Whether the power is out do to storms, you're camping and run out of juice, or you're in a Tom-Hanks-like Castaway situation, it's important to have a charged phone in case of an emergency.

Several established apps have received updates a few months ago that contained an unwanted add-on called either DU Quick Charge, DU Battery Boost, DU Boost Charge, DU Speed Charge, DU Speed Booster, or another name starting with DU.
The Nexus 6 has an AMOLED screen that uses virtually no power to display black pixels.

An atom is a basic unit of matter consisting of a dense, central nucleus surrounded by a cloud of negatively charged ions. The nucleus itself is a mixture of positively charged protons amd electrically neutral neutrons. Different groups of elements have respective atomic numbers. You can use the periodic table as a tool to draw atoms of elements. The periodic table is organized into periods, groups and families.

This video is a discourse about saltatory conduction in the neurons. According to the author, it begins with the opening of a gate on the membrane of one of the dendrites of a neuron, and positive charge enters through this gate. The positive charge spreads throughout the cell, and gets dissipated as it spreads, so that, by the time it reaches the Axon hillock of the neuron, it is left with very little potential. However, the potential which results from the simultaneous excitement of many de...
