Two rigid boxes containing different ideal gases are placed on a table . Box A contains one mole of nitrogen at temperature 𝑇_𝑜 , while box B contains one mole of helium at temperature 7/3 𝑇_𝑜 . The boxes are then put into thermal contact with each other and heat flows between them until the gases reach a common final temperature (ignore the heat capacity of boxes and heat exchange will happen only between boxes ) . Then the final temperature of the gases in terms of 𝑇_𝑜 is 7/3 𝑇_𝑜 3/2 𝑇_𝑜 5/2 𝑇_𝑜 3/7 𝑇_𝑜

1. using Kirchhoff law find the current in following branch answer     AB:(5/8) A, CA: (5/2) A, DEB: (15/8) A AD: (15/8) A, CD: 0 A, BC: (5/2) A 2.  using Kirchhoff law find the current in following branch   Answer  current in branch AB= (4/17) A In branch BC = (6/17) A In branch CD = (4/17) A In branch AD= (6/17) A In branch BD = (-2/17) A Total Current =(4/17) +(6/17)+(-4/17)+(6/17)+(-2/17)=(10/17) A 4. find R Equivalent
