What is the potential difference between currents lying on the same line, if the distance between them is 20 cm, and the strength of a uniform electric field is 40 kV / m?
To calculate the potential difference between the points presented, we use the formula: E = (φ1 – φ2) / d and φ1 – φ2 = E * d.
Variables: E – field strength (E = 40 kV / m = 40 * 10 ^ 3 V / m); d is the distance between the points presented (d = 20 cm = 0.2 m).
Calculation: φ1 – φ2 = E * d = 40 * 10 ^ 3 * 0.2 = 8 * 10 ^ 3 V = 8 kV.
Answer: The potential difference between the points shown is 8 kV.
