Electricity does not conduct through all liquids. Nonetheless, certain liquids are strong conductors of electricity while others are poor conductors. Water containing dissolved salts and minerals conducts electricity well, whereas pure water conducts electricity poorly. What liquids arent conductive? Distilled … Continue reading →

Don’t be misled into thinking higher octane gas contains less ethanol. In fact, it has more! The octane rating of pure ethanol is 100, but when it’s blended with gasoline, it performs as if it’s 112. In other words, higher-octane … Continue reading →

Rinse the affected area immediately with large amounts of water if acid … Continue reading →

AA and AAA batteries like NiMH and NiCd are easily charged in singles rather than pairs. The reason why they are charged in pairs is economy. Only one chargeing circuit is needed for every two batteries. This is a technique … Continue reading →

Lithium batteries have 3 stages of charging, usually divided into these three stages: Constant Current Pre-charge Mode. Constant Current Regulation Mode. What are 3 stages of battery charging? The three stages or steps in lead/acid battery charging are bulk, absorption, … Continue reading →

Soluble ionic compounds, strong acids, and weak bases are all electrolytes of varying strength. This is because they will all dissociate into ions to some degree in aqueous solutions. Nonelectrolytes are typically covalently bonded molecules that do not dissociate into … Continue reading →

The largest use for lead is in storage batteries in cars and other vehicles. Lead compounds are used as a pigment in paints, dyes, and ceramic glazes, and in caulk. Lead paint was banned for consumer use in 1978 in … Continue reading →

A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 … Continue reading →

remotes have their batteries in series so that if one cell is dead or missing the device will not work. Some devices, like my head-torch does use two AAA cells in parallel and the current supplied is thus equally shared … Continue reading →
