1. The problem statement, all variables and given/known data What is the current in the 2 ohms resistor? 2. Relevant equations Kirchhoff's loop law 3. The attempt at a solution Grounding does not affect how the circuit behaves, so I ignored the ground in and applied the loop law (clockwise from the negative terminal of the 9V battery ): ΔV(loop) = 9V -(2 ohms)*I - 3V - (4 ohms)*I =0 6V = (6 ohms)*I I = 1 A Correct?
