Why germanium is not used for making power electronic devices?
its because the gallium emites heat and a negligable photon energy
What is the most fun electronic device?
all electronic devices are fun electronic devices when we use them funnly
What is phantom energy?
These devices contribute to the energy-wasting phenomenon called "phantom power," or vampire energy. Simply put, this is the power that is used when electronic devices draw energy from the grid into your home just by being plugged in, when you aren't looking and you aren't using them. Many electronic devices continue to draw power even when not in use. Energy drawn by the standby mode sometimes is referred to as a "phantom load." An estimated 50 percent of the energy used by an electronic device is drawn while the device is not in use, making phantom loads responsible for 4 to 7 percent of your total electricity use. Phantom loads can be reduced in many ways, some of them for little cost or free.
What is the purpose of using a power Jack?
A power jack is used to transfer electrical energy to an electronic device for use. Often jacks are used on smaller devices that have lower electrical requirements.
What is the common problem associated with power surges?
damage to electronic devices
What are power system transients?
Power system transients are voltage or current spikes, sudden and brief increases or decreases in the supplied power. These can be harmful for some types of electronic devices, and can be seen by a brief flicker of either dimmer or brighter light from light bulbs.
How is fossil fuels used to produce energy?
when we burn fossil fuels such as oil,gas and coal we produce heat.This can be used to fuel power plants which is where most of our energy for electronic devices and heating are funded
Where can one find power monitoring devices?
Power monitoring devices can be found at local electronic stores and most hardware stores. Websites such as Newegg and Amazon also carry power monitoring devices.
Which does not state a principle related to why ground wires are in effective safety device?
Electronic devices are protected from power surges by having insulated wires
What are the active electronic components?
Active devices are those devices which can produce power or which can amplify the signal Such devices are- diode transistor op-amp
What is the meaning of smps?
SMPS stands for Switched-Mode Power Supply. It is an electronic power supply that efficiently converts electrical power using switching devices such as transistors. SMPS are commonly used in electronic devices to provide stable and regulated power to sensitive components.
Will an HDTV USB port power most devices such as a USB desk fan?
Yes, in most cases, it will likely power the fan and most electronic devices.
