Homework Statement
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.
Homework Equations
Kirchhoff's voltage law says the total voltage around a closed loop must be zero.
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?
