How can I calculate ideal values of current for both short and open circuits by using Ohm’s law.
Further more usually said that it is not advisable to connect DC batteries of different voltages in parallel can you explain it for me in the light of Ohm’s law?
edit:
A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an excessive electric current limited only by the Thévenin equivalent resistance of the rest of the network and potentially causes circuit damage, overheating, fire or explosion. Although usually the result of a fault, there are cases where short circuits are caused intentionally, for example, for the purpose of voltage-sensing crowbar circuit protectors. while an open electric circuit through which current cannot flow because the path is broken or interrupted by an opening.
