Questions & Step-by-Step Solutions

If the electric potential at a point is 150 V and the electric field is uniform, what is the potential difference over a distance of 3 m?
  • Step 1: Understand that electric potential (V) is given as 150 V at a point.
  • Step 2: Recognize that the electric field (E) can be calculated using the formula E = V / d, where d is the distance.
  • Step 3: Since we want to find the potential difference (ΔV) over a distance of 3 m, we can use the formula ΔV = E * d.
  • Step 4: Calculate the electric field (E) using the given potential and distance: E = 150 V / 3 m = 50 V/m.
  • Step 5: Now, use the electric field to find the potential difference over 3 m: ΔV = E * d = 50 V/m * 3 m.
  • Step 6: Calculate ΔV: 50 V/m * 3 m = 150 V.
