Liquid nitrogen is passed through the tube and by condensing moisture reduces the load on the vacuum pump. When too great a layer of ice has formed on the tube is simply defrosted by the passage of an electric current through the metal tube. 展开 ...
Electricity is an important part of our daily lives. A simple electrical circuit consists of several essential elements. The power source, such as a battery, provides the energy to make the current flow. The wires act as conductors to carry the electric current from the power source to the ...

In addition to storing electric charges, capacitors feature the important ability to block DC current while passing AC current, and are used in a variety of ways in electronic circuits. Most noises that cause electronic devices to malfunction are high-fr
aOne of the most fundamental concepts in electric circuit analysis is that of charge conservation.We know from basic physics that there are two types of charge:positive (corresponding to a proton),and negative (corresponding to electron).For the most part,this test is concerned with circuits in...
