1. The problem statement, all variables and given/known data Using kirchhoff's laws, calculate the current in the 2 ohm resistor. Picture of the circuit attached. 2. Relevant equations kirchhoff's laws, and ohms law 3. The attempt at a solution i3 = i1 - i2 then i used kirchhoff's law to get: 2 - i1 = 2.i2 and 1 - 2 ( i1 - i2 ) + 2.i2 = 0 [i added the value because the direction of the "potential walk" is opposite to the current through the resistor] using these, i obtained a value of 0.375A as the current i2, but the book says that the answer is 0.42A, have i made a mistake, or is the book wrong [again!]?
