The definition of an ionic compound, is a chemical compound composed of ions held together by electrostatic forces – basically held together by ionic bonds. They are formed by neatly packed ions of opposite charge. The compound is neutral, but … Continue reading →

Covalent molecular substances which are acidic or basic react with water producing free mobile atoms. The resulting ions are able to move freely throughout the solution carrying charge and hence conducting an electric current. Why do some molecular compounds conduct … Continue reading →

Materials conduct electricity if one of two things happens: If electrons can move around freely (as in the delocalized bonds of metals), then electricity can be conducted. If ions can move around freely, electricity can be conducted. Why do some … Continue reading →

Pencil lead is not lead at all; it’s a combination of finely ground graphite and clay, mixed with water and pressed together at high temperatures into thin rods. We call it lead is because the Englishmen who first discovered graphite … Continue reading →

The most recent research indicates that lead can damage the infant brain even at blood levels as low as 5 μ/dl (5). These findings, together with data showing that lead can damage the catalytic converters of cars, have triggered strong … Continue reading →

Pros and Cons of Solar Energy Advantages of Solar Energy Disadvantages of Solar Energy Renewable Energy Source Cost Reduces Electricity Bills Weather Dependent Diverse Applications Solar Energy Storage is Expensive Low Maintenance Costs Uses a Lot of Space What is … Continue reading →

About 60% of the weight of an automotive-type lead–acid battery rated around 60 A·h is lead or internal parts made of lead; the balance is electrolyte, separators, and the case. Is car battery lead pure? Battery Glossary – Pure Lead … Continue reading →

60% of the battery is made up of a combination of materials like zinc (anode), manganese (cathode) and potassium. These materials are all earth elements. This combination of material is 100% recovered and reused as a micro-nutrient in the production … Continue reading →

When a battery is expired, it means that the battery’s manufacturer can no longer guarantee that the battery has a full life or charge. More specifically battery expiration dates are based upon when the battery’s total self-discharge will exceed 20%. … Continue reading →

Not all lead acid batteries are nominally the 12V variety. Common battery voltages available are 6, 12, 18, 24 Volts et al. A fully charged cell is 2.14 Volts. At what voltage is a 12V lead acid battery fully charged? … Continue reading →

A single car has about 30,000 parts, counting every part down to the smallest screws, nuts and bolts. Some of these parts are made by the manufacturer, but there are lots of suppliers that make many of these parts. The … Continue reading →

Nevertheless, lithium-ion batteries can have a higher energy density than sodium-ion batteries and are smaller and lighter. This is where sodium batteries are inherently inferior to lithium batteries. Why is lithium better than sodium for batteries? Sodium-ion batteries offer better … Continue reading →

The most popular car battery is the 063 Type (UK reference number) which is around 21 cm long x 17.5 wide x 17.5 high. The 063 is a 12 volt car battery and generally delivers 42ah, 43ah or 44ah depending … Continue reading →

Interlock is a current and voltage loop mechanism used to detect tampering or opening of the high-voltage equipment or service disconnect switch. What is hybrid interlock? The hybrid vehicle interlock circuit is designed to disable engine start for safety reasons. … Continue reading →

Capacities for two common sizes: Single Gang Boxes: A total capacity of 18 cubic inches allows for nine #14 gauge wires, eight #12 gauge wires, or seven #10 gauge wires. This is a wires-only capacity. With one device added to … Continue reading →
