1.Forward-Biased:When you insert a battery correctly into a circuit, current will be allowed to flow through a diode; this is called a forward-biased state. 2.Reverse-Biased:When you slip a battery into a circuit backward, your diode will block any current from flowing, which is called a...

How does a transformer work?A transformer is based on a very simple fact about electricity: when a fluctuating electric current flows through a wire, it generates a magnetic field (an invisible pattern of magnetism) or "magnetic flux" all around it. The strength of the magnetism (which has ...
When you get an electric shock, it interrupts the normal operation of the system, sort of like a power surge. A shock at the lightning level can cause your body to stop. The electrical process doesn't work anymore — it's fried. But that’s a story for another time. Human Body Makes...
How long does a laptop battery last? The lifespan of a laptop battery depends on several factors, including its type, age, and usage patterns. On average, a laptop battery can last between 2-5 years or between 300-500 charge cycles. However, this can vary depending on how often you use...
How does a fuel cell work?Tony LeoSeptember 21, 2022What is a fuel cell?A fuel cell is a device that makes electricity from fuel and air. Instead of burning the fuel to make heat to drive a mechanical generator, fuel cells react the fuel and air electrochemically, without combustion. ...
To explain how a BMS works let’s take a look at how a typical e-bike battery is constructed. The basic building block is a 18650 Li-ion cell: Fig.1 One cell does not contain enough energy to power an e-bike. One cell typically has a nominal voltage of 3.7 V and a capacity of...
How Does a DC Generator Work? The working principle of a DC generator can be explained as follows: When the generator is driven by a prime mover, such as an engine or turbine, the shaft rotates along with the armature. As the armature rotates, the conductors cut through the magnetic field...
The electric engine of an EV does not need to pressurize and burn gasoline to drive the car’s wheels. Instead, it generates rotational force by using electromagnets inside the motor that are driven by a battery. There are two sets of magnets within the motor. One pair is linked to the ...
Power companies save a great deal of money this way, using very high voltages to transmit power over long distances. How does this work? Well, let's say that you have a power plant that can produce 1 million watts of power. One way to transmit that power would be to send 1 million ...
