General Physics MCQ with Answers

Silver plated copper is also commonly used. As a rule, fuse elements of time delay fuses contain low melting point materials, e.g. tin (Sn) or zinc (Zn) and alloys

Yellow and Blue

In the process of the reaction, electrons can be transferred from the zinc to the copper through an electrically conducting path as a useful electric current. An electrochemical cell can be created by placing metallic electrodes into an electrolyte where a chemical reaction either uses or generates an electric current

speed is inversely prortional to time. So, if speed is 4 times the time taken is one-fourth

for arc welding dc voltage required is 200 to 250 V
