Recall Questions Define potential difference?? Energy transfer per unit charge from electrical to other forms. Define the volt?? $$1V = 1JC^{-1}$$ Define electromotive force of a source such as a cell or a power supply?? Energy transfer per unit charge from chemical/other to electrical form. Define resistance?? $$\frac{\text{potential difference}}{\text{current}}$$ Define the ohm?? A component has a resistance of $1\Omega$ is a potential difference of $1V$ makes a current of $1A$ flow through it. Define resistivity of a material?
