Whereas an alkaline battery may drop from “powering” to “dead” pretty quickly, a rechargeable battery may hang on at a lower voltage for slightly longer, resulting in unexpected behavior such as dimming lights or a clock that can’t keep time. … Continue reading →

Explanation: Bases that are soluble in water are called alkalis. For example, sodium hydroxide, potassium hydroxide, calcium hydroxide are soluble in water.But bases like copper hydroxide Cu(OH)2 ferric hydroxide (Fe(OH)3) aluminium hydroxide (Al(OH)3)do not dissolve in water. They are, therefore, … Continue reading →

Make sure the charger is off. Hook-up the positive cable on the charger to the positive terminal on the battery. Hook up the negative cable on the charger to the negative terminal on the battery. Set the charger to the … Continue reading →

Electrical motors are wound with copper wire. Copper has high thermal conductivity. This makes it a good material for car radiator, which is used for cooling engines by transferring heat from the coolant to the air. The radiator can also … Continue reading →
