A surge suppressor is a device that is installed in an electrical circuit to protect against voltage spikes. These devices are also known as surge protectors or voltage suppressors. Surge suppressors are designed to absorb the excess energy from a voltage spike and dissipate it safely away from sensitive electronic components. Do surge suppressors work? … Read more
DDE is a mechanism for applications to share data. It is a client-server protocol, with the server providing data and the client requesting data. DDE is used in a number of different ways. One common use is for spreadsheet applications to share data. For example, a user may have a spreadsheet open in one application, … Read more
Polarization is the Waves property of having a preferred direction. The vibrations of an electromagnetic wave are perpendicular to the direction of the wave. The polarization of an electromagnetic wave is the direction of the electric field vector. The electric field vector of an electromagnetic wave is perpendicular to the direction of the wave. The … Read more
The Carbon Reduction Commitment (CRC) is a UK-wide scheme to encourage large businesses and public sector organisations to reduce their carbon emissions. It began in 2010 and will run until 2027. Organisations that participate in the CRC must submit an annual report detailing their emissions and purchase allowances to cover their emissions. The cost of … Read more
The dielectric constant, also known as the permittivity, is a measure of how easily a material can be polarized by an electric field. The higher the dielectric constant, the more easily the material can be polarized. The dielectric constant is a key parameter in determining the capacitance of a capacitor, the inductance of a coil, … Read more
A picofarad per meter (pF/m) is a unit of electrical impedance of a material. It is the reciprocal of the capacitance per unit length of a material. The SI unit of electrical impedance is the ohm. What is P farad? The P in P farad stands for “permanent”. A permanent farad is a unit of … Read more
True power is the power required by a load to perform its essential function. It is the power that a load must draw from a power source to operate at its specified voltage and current, and is usually expressed in watts (W). A load’s true power requirements may be different from its apparent power requirements, … Read more
An electric charge is a physical property of matter that causes it to interact with other matter via the electromagnetic force. The presence of an electric charge, which can be either positive or negative, creates an electric field. The movement of electric charges is an electric current. Electric charges come in two types: positive and … Read more
