1. The problem statement, all variables and given/known data 2. Relevant equations Ohm's Law R = V/I V = IR 3. The attempt at a solution here is my answer, i have a feeling im missing something, any help would be appreciated. The graph represents a linear relationship between the potential difference (V) and the current (A). By calculating the slope of the graph, you will get the value of the resistance in Ohms. The slope of the graph is constant, demonstrating that the resistance (R) is constant as well. I just started learning about electricity and magnetism, and im not really understanding what potential difference means, its making questions like these seem really confusing. Correct me if im wrong, but from what i read, potential difference is either the amount of energy required to move a coulomb of charge from one point to another in a circuit, but then my lesson also says that potential difference is the decrease in electrical potential energy for each coulomb in a circuit. Im a bit confused, can someone explain to me (in english) what potential difference is??
