There are two types of capacitive touchscreens; surface capacitive and projected capacitive. A surface capacitive touchscreen uses a transparent layer of conductive film overlaid onto a glass sublayer. What are the two types of touch screen? 4 Touch Panel Types … Continue reading →

A portable power station is the best option if you need to juice up common personal electronics and small appliances while spending long periods of time away from household AC outlets, or if you want to have backup power ready … Continue reading →

You need a common ground for two batteries in parallel by definition. In order for them to be in parallel, their grounds must be connected to each other (and to the – side of the motor) and their positives must … Continue reading →

approximately 28 hours. Your 4A charger will slowly charge up your 110Ah leisure battery, but perhaps not in the best possible way if it is heavily discharged. From flat, it could take approximately 28 hours to charge (110/4). How long … Continue reading →

No. US stocks are not being listed in India. Instead, NSE is listing its derivative product called NSE IFSC Receipts. The NSE IFSC (NSE International Exchange) will be offering trading in these receipts at a ‘low cost’. Can I buy … Continue reading →

For applications where life times exceeding 10 years are expected, GEL batteries are the better choice. Flat plate GEL types are for high current discharges, and tubular plate types should be used for discharges of one hour or more. This … Continue reading →

Using metal ions with three or more positive charges, researchers in Tian’s laboratory bonded graphene-oxide flakes into a transparent membrane. This new form of carbon-polymer sheet is flexible, nontoxic and mechanically strong, in addition to being non-flammable. Why is graphene … Continue reading →

Graphite is used for the anodes of lithium-ion batteries because of its elec- trical and thermal conductivity. Bastnaesite is a source of rare-earth elements used to produce magnets in speakers, microphones, and vibration motors. How is graphene used in phones? … Continue reading →
