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. WebApr 8, 2024 · Current flowing from the cell is, I = 0.37 A. The relationship between emf of a cell, potential difference, current & internal resistance is given as, e = V + Ir. After rearranging the equation we can write; e – V = Ir. (e – V)/I = r. Therefore we see that r = (3.0 – 2.8)/0.37 = 0.54 Ohm. Now due to the Internal Resistance which is of the ...
WebIt says that the voltage between two points of a conductor is directly proportional to the current flowing through it as long as its physical properties remain constant. This is expressed in the form of the equation: V = IR. where V is the potential difference, I is the current flowing, and R is the constant proportionality factor, which is ...
