Answer Posted / unath
Emf is the energy supplied to charge by some active device like battery. for eg. emf of a device is 2 volt means the device supplies 2 joules energy to one coulomb. On the other hand, potential difference between two points A & B is 2 volts means, 1 coulomb of charge will give up an energy of 2 joule when moving from A to B.

54 Comments Alok and Bhanu play the following min-max game. Given the expression N = 38 + X*(Y – Z) where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be?
