1. The problem statement, all variables and given/known data Hi, I'm learning about Kirchhoff's laws, and have to solve the circuit. Attached picture of part the circuit I am attempting to solve. The ammeter reads 2 A. 2. Relevant equations Kirchhoff's voltage law says the total voltage around a closed loop must be zero. 3. The attempt at a solution By going around the loop I get 0 = -18V + (7 ohms)(I1) + (5 ohms)(2 A) + 3V. Then solving for the current I1 I find that it is -0.714 A. But in the solution it does not have a negative sign. What did I do wrong?
