A magnetic field is a vector field that describes the magnetic force on a moving electric charge in the presence of an electric field. The magnetic field is produced by moving electric charges and the moving charges produce the magnetic field. What is the magnetic field and why is it important? The magnetic field is … Read more
Debouncing is a technique often used to clean up switch inputs. When a switch is pressed, the input signal can often bounce around for a short period of time before settling at the new, pressed state. This bouncing can cause issues if the switch is being used to trigger an action, since the action may … Read more
The motive power of a device is the power required to move it. In the case of an electronic device, the motive power is the power required to move the electrons through the device. This can be thought of as the power required to overcome the resistance of the device. The motive power can be … Read more
The electric field strength is the force exerted by an electric field on a charged particle, divided by the particle’s charge. The SI unit for electric field strength is the volt per meter (V/m). What is the SI unit of electric field strength? The SI unit of electric field strength is the volt per meter … Read more
An LED light bulb is a light bulb that uses light-emitting diodes (LEDs) as its source of light. LED light bulbs are more energy-efficient and have a longer lifespan than traditional incandescent light bulbs. What are the 3 types of LED light bulbs? There are three types of LED (light-emitting diode) bulbs: standard, candelabra, and … Read more
Potential energy (U) is the energy stored in an electric field. It is the energy that would be released if the electric field were to collapse. Why is potential energy written as U? The potential energy of a system is the energy that it has the potential to release. Potential energy is stored energy, and … Read more
An amplification factor (gain) is a number that represents how much an electronic signal has been amplified. The gain can be expressed as a ratio, such as 2:1, which means that the signal has been amplified by a factor of two. The gain can also be expressed as a percentage, such as 100%, which means … Read more
The term “degauss” refers to the process of removing or reducing the magnetic field in a piece of electronic equipment. This can be done manually, using a degaussing coil, or automatically, using a degaussing circuit. Degaussing is necessary because magnetic fields can interfere with the proper functioning of electronic equipment. What does degauss mean in … Read more
In quantum mechanics, entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently of the state of the others. What is an example of a entanglement? In quantum mechanics, entanglement is a phenomenon in … Read more
The charge quantity is a measure of the amount of charge that is flowing through a given circuit. It is typically measured in terms of the number of electrons that are passing through the circuit per unit time. The charge quantity can be used to determine the amount of current that is flowing through a … Read more
