A positive number on the ammeter means that more electricity is being received by the battery than is being used, suggesting the regulator is not working efficiently (or at all if it’s a large positive number). What is positive and … Continue reading →

Lithium-ion batteries are incredibly popular these days. You can find them not just on smartphones but on laptops, PDAs, cars, and iPods. Most smartphone brands including Samsung, iPhone, Infinix, Nokia use lithium-ion batteries. Do all phones have lithium batteries? Lithium-ion … Continue reading →

One of the benefits of DEWALT XRP™ Lithium Ion batteries is that they have limited self discharge. Storing DEWALT Lithium Ion batteries outside of the charger will not result in loss of charge. Learn more about brushless tools technology. Are … Continue reading →

Samsung’s Galaxy M31 packs a gigantic 6,000mAh battery, which is 900mAh bigger than the Lenovo P2’s. And we won’t keep you in suspense: this larger battery meant the Galaxy lasted for 30hrs 20mins in our video-rundown test, beating the P2 … Continue reading →

Nanotechnology offers the potential for new and faster kinds of computers, more efficient power sources and life-saving medical treatments. Potential disadvantages include economic disruption and possible threats to security, privacy, health and the environment. What are the negative effects of … Continue reading →

The electromotive force (emf) is the sum of the electric potential differences produced by a separation of charges (electrons or ions) that can occur at each phase boundary (or interface) in the cell. What is EMF of a cell class … Continue reading →

Nanotechnology is science and engineering at the scale of atoms and molecules. It is the manipulation and use of materials and devices so tiny that nothing can be built any smaller. What is a simple definition of nanotechnology? : the … Continue reading →

The emf of a cell is the sum of the electric potential differences (PDs) produced by a separation of charges (electrons or ions) that can occur at each phase boundary (or interface) in the cell. The magnitude of each PD … Continue reading →

Correct answer: Galvanic cells have positive voltage potentials, while electrolytic voltage potentials are negative. Both types of cell, however, have oxidation occur at the cathode and reduction occur at the anode. Which is not true about galvanic cell? Question: Which … Continue reading →

Lung problems, including pneumonia or interstitial lung disease (scarring in your lungs). Bleeding more easily than usual. Suicidal thoughts and actions.*† Discontinuation … Continue reading →

Do not use an MAO inhibitor within 14 days before or 14 days after you take bupropion. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, phenelzine, rasagiline, selegiline, and tranylcypromine. Do not take bupropion to treat more … Continue reading →

Some products that may interact with this drug include: certain antidepressants (such as amitriptyline, nortriptyline, phenelzine), certain antibiotics (carbapenems such as imipenem), irinotecan, mefloquine, orlistat, other medications for seizure (such as ethosuximide, lamotrigine, phenytoin, rufinamide, topiramate), What is contraindicated with … Continue reading →

Several kinds of all-solid state batteries are likely to come to market as technological progress continues. The first will be solid state batteries with graphite-based anodes, bringing improved energy performance and safety. What materials do solid-state batteries use? Materials proposed … Continue reading →

Charging a Lithium Ion battery with a lab bench power supply is possible only under very controlled conditions. It is also possible only with a lab bench power supply that has both, constant current and constant voltage feature. Can I … Continue reading →
