Current and potential difference equation

WebFigure 6: Measuring Potential Difference. D. Summary. Electric current is the rate of flow of a charge: I=Q/t. Conventional current is a flow of charges from positive to negative terminals. The coulomb is the unit of charge and is equivalent to an ampere-second. Charges can be calculated using the equation Q=It. For a current-carrying conductor ... WebMay 9, 2024 · We can make the relationship between potential difference and the magnetic field explicit by substituting the right side of Equation 2.5.1 into Equation 2.5.2, yielding. ΔW ≈ q[v × B(r)] ⋅ ˆlΔl. Equation 2.5.3 gives the work only for a short distance around r. Now let us try to generalize this result.
