You can typically identify a USB 3. x port or connector by its blue coloring. Some USB 3.0 ports also have an SS symbol (which stands for Super Speed). Most new computers have at least one USB 3 port, and … Continue reading →

The USB 2.0 specification limits the length of a cable between USB 2.0 devices (full-speed or hi-speed) to 5 meters (or about 16 feet and 5 inches). How far can you extend USB power? USB 2.0 cables can be extended … Continue reading →

“My battery is low and it’s getting dark.” This supposedly was the last message sent back to mission controllers on Earth by the Mars Exploration Rover Opportunity. When was Opportunity’s last message? June 10, 2018The final communication from the rover … Continue reading →

Raise amps from a given voltage source by lowering resistance. An ordinary car battery will provide plenty amperage for electrolysis. If you need more still, hook up a second battery in parallel. How do you increase amperage in a battery? … Continue reading →

Transuranic wastes, sometimes called TRU, account for most of the radioactive hazard remaining in high-level waste after 1,000 years. Radioactive isotopes eventually decay, or disintegrate, to harmless materials. Some isotopes decay in hours or even minutes, but others decay very … Continue reading →

The Federal Communications Commission (FCC) — which regulates cell phones, among other things, in the United States — has set radiation standards for cell phones at 1.6 watts per kilogram averaged over 1 gram of tissue. Do cell phones emit … Continue reading →

Ordering Uranium or Thorium Compounds By regulation, the general public is allowed to order these materials without possessing a radioactive materials license, so vendors will sell these compounds directly to any customer. Can civilians buy uranium? Yes, you have to … Continue reading →

Therefore boosting the amperage in an electric circuit can be accomplished through two separate means. Because voltage equals the amperage multiplied by the resistance in a circuit, if the voltage remains constant and the resistance is dropped, the amperage across … Continue reading →

Workhorse Group has received a consensus rating of Buy. The company’s average rating score is 2.57, and is based on 4 buy ratings, 3 hold ratings, and no sell ratings. Is workhorse good stock to buy? Is Workhorse Group Inc … Continue reading →

Graphene is a single layer (monolayer) of carbon atoms, tightly bound in a hexagonal honeycomb lattice. It is an allotrope of carbon in the form of a plane of sp2-bonded atoms with a molecular bond length of 0.142 nanometres. Is … Continue reading →

for example, according to CEC anything above 750V is considered high voltage. What is considered as high voltage? In the context of building wiring and the general use of an electrical apparatus, the International Electrotechnical Commission defines high voltage as … Continue reading →

No matter your circuit and its operating conditions, the current going out of the battery should be equal to the current going in. The voltage only changes because the chemicals inside the cell are changed slightly and not because of … Continue reading →

The structure of boron nitride in its wurtzite configuration is stronger than diamonds. Boron nitride can also be used to construct nanotubes, aerogels, and a wide variety of other fascinating applications. Is there something stronger than a diamond? Moissanite, a … Continue reading →

If the motor had just been running and just switched off it should have 14.0V. Left standing with everything off overnight, it will settle down to 12.8V. After a week’s standing it will droop to 12.6V, depending on ambient temperature. … Continue reading →

GAC introduces the Aion V, its first-ever model with a graphene battery. The traditional lithium-ion battery could soon be replaced in electric cars by a new generation made from graphene. This material has many qualities. In particular, it should allow … Continue reading →
