What is the net electric flux through the surface? The net flux through a closed surface is a quantitative measure of the net charge inside a closed surface. … The net electric flux is zero through any closed surface surrounding a zero net charge. Therefore, if we know the net flux across a closed surface, then we know the net charge enclosed.
What do you specialize in electrical engineering? Other electrical engineering specializations include semiconductors, nanoelectronics, electrophysics, microsystems, optics and photonics, signal and image processing, network systems, computer networking, remote sensing and space systems, circuits and Very Large Scale Integration (VLSI).
What is the best specialty in electrical engineering? There are many sub-disciplines of electrical engineering. Some electrical engineers specialize exclusively in one sub-discipline, while others specialize in a combination of sub-disciplines.
Do electrical engineers specialize? Electrical engineering has now subdivided into a wide range of subfields including electronics, digital computers, computer engineering, power engineering, telecommunications, control systems, robotics, radio-frequency engineering, signal processing, instrumentation, and microelectronics.

How to kitten proof electrical cords?
Use plastic cord management covers. These are good for covering the cords completely where they run along a wall or across the floor. Wrap cords with double-sided tape. Cats do not like the stickiness of the tape, so they wouldn’t want to play with it.
How much electricity is needed to extract hydrogen from water?
However, current best processes for water electrolysis have an effective electrical efficiency of 70-80%, so that producing 1 kg of hydrogen (which has a specific energy of 143 MJ/kg or about 40 kWh/kg) requires 50–55 kWh of electricity.
How much money do universities have to pay for electricity?
Colleges and universities in the U.S. spend an average of $1.10 per square foot (ft2) on electricity and 18¢/ft2 on natural gas annually.
Why are australian electricity prices so high?
Over the past decade, electricity prices in Australia have increased by 63 per cent on top of inflation. One of the main reasons for this is access to electricity. … These costs make up the largest component of an electricity bill in all states except for South Australia, where generation costs are higher.
Is an electrical engineering degree the same as electronic engineering?
Electrical engineering is the broader field, and it includes electronics engineering as well as other areas, such as power systems, signal processing, and communications. Electronics engineering is typically more focused specifically on the design, optimization, and management of electronic devices.
How are hydrogen fuel cells used to run electric motors?
Essentially, there are no moving parts, it’s just the chemical reaction that ‘fuels’ the action. It sees hydrogen enter the fuel cell from a tank and mix with oxygen to create H2O in a chemical reaction, which generates electricity that is used to power the motors that drive the wheels.
Where to find electric meter apartment?
Your meter might be located inside or outside. If your meter is not mounted outside where the power lines come into your home, please check for your electric meter in your basement, laundry room, porch, garage, closet or attic.
Why is my electric stair keep going in?
Please check that your stairlift is parked in the correct position at the charging point (which is usually at the top or bottom of the stairs). Also check that the wall switch and mains power switch is on or that there has not been a power cut.
Can electric oven emit carbon monoxide?
An electric oven is powered by electricity, not gas, and is safer to leave running than an older gas stove because it doesn’t emit carbon monoxide. Electric ovens frequently stay on for many hours at a time without adverse effects. … Opening the oven door will allow the heat to move more freely into the room.
Can polymers conduct electricity?
Conductive polymers or, more precisely, intrinsically conducting polymers (ICPs) are organic polymers that conduct electricity. Such compounds may have metallic conductivity or can be semiconductors. The biggest advantage of conductive polymers is their processability, mainly by dispersion.
What voltage is a electric car?
You can charge your electric car using standard 120 volt(V) home outlets (Level 1), 208-240V outlets like those used by your dryer (Level 2), or dedicated 480V+ public fast chargers (DC Fast Charging). The time it takes to charge using each of these three options depends on your drive and the size of the battery.
What does ze mean in electrical terms?
How to test External Earth Fault Loop Impedance (Ze)? `Ze` is a measurement of the external earth fault impedance of the installation. It is the measured resistance of the supply transformer winding, the supply phase conductor, and the erath return path of the supply.
Who discovered the connection between electricity and magnetism?
Oersted made the discovery for which he is famous in 1820. At the time, although most scientists thought electricity and magnetism were not related, there were some reasons to think there might be a connection.
Do ionic compounds conduct electricity as?
Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.
What kind of electric outlet are in china?
For China there are three associated plug types, types A, C and I. Plug type A is the plug which has two flat parallel pins, plug type C is the plug which has two round pins and plug type I is the plug which has three flat pins in a triangular pattern. China operates on a 220V supply voltage and 50Hz.
Can paper be electrically charged?
The bits of paper are electrically neutral, but when you bring the rod close to them, even though paper is not a conductor, that is, the charges within it are not free to move about as a current, the negative charges have enough mobility that they are repelled by the rod.
Who is known as the father of electricity?
The Father of Electricity, Michael Faraday was born on September 22, in 1791. The English scientist, who is responsible for the discovery of electromagnetic induction, electrolysis and diamagnetism, hailed from a poor family of a blacksmith.
Can squirrel short out electric?
When a squirrel happens to make inappropriate contact with a power line, conductor or other high voltage equipment, they are often electrocuted. The result? Shorted out circuits which often completely shut down the equipment.
What device protects your electric motor?
Circuit breakers and fuses are use as protection units for the different motors. Overcurrent protection can protect personnel from electric shock, the control equipment of the motor, the conductors of the motor branch circuits and the motor itself from high currents.
