Answer to Question #20100 in Electromagnetism for B Vamshi
1.Resistances of 2ohms and 3 ohms are connected in series between terminals A and B, and a potential difference of 20 V is applied between the terminals. An unknown resistance is connected in parallel to the 3 ohms resistance and the current in this unknown resistance is 5/12 times the current that was flowing from A to B before it was connected. Find the unknown resistance.
