What happens when my ebike battery dies? When your battery is dead, there will be no power to the bike at all. So, your electric headlight and brake light won’t turn on. And you won’t be able to charge your … Continue reading →

The formula is (A)*(h)*1000 =(mAh). For example, if you have a current of 3 A running for 5 hours, the number of mAh is 3A*5h*1000 = 15000mAh. How is mAh usage calculated? If instead of the current you have voltage … Continue reading →

Here’s a little known fact: The human body, at any given moment, produces energy equivalent to a 100 watt light bulb. In that sense, we’re always wasting our energy—energy that can be used to, well, power a light bulb. Can … Continue reading →

These are the reasons why new Christmas light strands are wired in parallel. Parallel wiring allows for several paths that electricity can take to get from the energy source to where the power is grounded. Even with several strings of … Continue reading →

These generalizations have led to many believing that 1-watt, 3-watt and 5-watt LEDs are different LEDs; it has also led to the belief that 350mA is always equal to 1-watt, 700mA is equal to 3-watts and 1000mA is equal to … Continue reading →

Originally Answered: Is copper wire really pure copper? If not, what is it made of? Not only is it pure copper, it is >99.95% pure copper. The electrical conductivity is dependent on the purity of the metal, and even a … Continue reading →

Electrical circuit with lemons. A chemical reaction between the copper and zinc plates and the citric acid produces a small current, that is able to power a light bulb. Why do lemons make a battery? The citric acid of the … Continue reading →

Electricity could be discovered using batteries based on zinc or lead, but without copper wiring it would remain little more than a scientific curiosity. Electric motors and generators require large amount of wiring, so they are impossible to build on … Continue reading →

Life on earth is carbon-based, but carbon-based life is impossible without metals. All living organisms, without exception, need metals to live. And so, all organisms must carefully manage their metal nutrition. What will happen if there is no metal? metals … Continue reading →
