Copper and Copper alloys are some of the most versatile engineering materials available. The combination of physical … Continue reading →

Because it has even less chance of overheating, 12-gauge wire is also acceptable on a 15-amp circuit. What happens when you use a 12 gauge wire on a 15 amp circuit? If you are using 15 amp breaker, and 15 … Continue reading →

Copper may not be strong, but it is not easy to break due to its high toughness. This property comes in handy for piping and tube applications, where a rupture can be dangerous and expensive. What can break down copper? … Continue reading →

You can overload a 15 amp receptacle if you use it to power an appliance that draws 20 amps or more. But a 20 amp plug cannot fit in a 15 amp outlet, to begin with. If you force a … Continue reading →

1.14048 hours. Therefore, with a load of 500W, the 3kVA will last for 1.14048 hours ( approximately 68.4 minutes ). This about 52% more time than that of the 2kVA Online UPS. What is the capacity of a 3KVA inverter? … Continue reading →

Digital inverter compressor involves 4 friction point whereas by using electromagnet setup, linear inverter compressor reduces friction point to just 1. This reduces the wastage of energy and translates into high energy efficiency. Which type of compressor is best for … Continue reading →

A simple rule of thumb is to take 100 sqft for every 1kW of solar panels. Extrapolating this, a 1 MW solar PV power plant should require about 100000 sqft (about 2.5 acres, or 1 hectare). How many acres is … Continue reading →

What materials do you need to make a lemon battery? To make a multi-cell lemon battery you will need four copper pennies, four galvanized nails, four lemons, a knife, 15 inches of copper wire, wire cutters, a ruler, and a … Continue reading →

Zinc metal can dissolve to form zinc ions, releasing energy; it also loses electrons. Does zinc give or take electrons? Zinc exhibits only the +2 oxidation state. It can give up two electrons to form an electrovalent compound; e.g., zinc … Continue reading →

A 5000-watt inverter would require a minimum 450 to 500 ah 12 V battery. Alternatively, you can have two separate batteries of 210ah 12V that would power the system for 30 to 45 minutes. If you demand to run the … Continue reading →

Kilowatt hour. The basic unit of electricity is the Kilowatt hour (kWh). In simple terms, 1 kWh is the amount of energy used by a 1kW (1000 watt) electric heater for 1 hour. Another example is ten 100-watt light bulbs … Continue reading →
