What is the difference between an short circuit and a closed circuit?

You know there is a differnce. The dynamic short circuit is dynamic and the static short circuit is static. It's common sense really.dyanamic means when due to some external source theresistance becomes zero ,can be through anythin due to high supply of current or anything,the current in that circiut becomes infinite and that result s in short circuiting. Static short circuit means when through the different changes in the voltage makes the resistance zero and current infinite ,

V = I/R

WHERE R= 0

AND CURRENT BECOMES INFINIT AND THAT RESULT IN A

SHORT CIRCUIT
