Questions & Answers
Q: How does the electric field between parallel plates differ from point charges?
The electric field between parallel plates is uniform, unlike the varying electric field around point charges. It remains consistent between the plates as long as you are near the middle.
Q: What is the equation used to calculate electric field strength for parallel plates?
The equation relates electric field strength (E), potential difference (ΔV), and plate separation (d). It can only be applied to parallel plates due to the uniform field.
Q: How is the formula rearranged to determine the potential difference across the plates?
By rearranging the equation, ΔV = E * d, where E is the electric field strength in volts per meter and d is the distance between the plates converted to meters.
Q: In the given example, what voltage is needed across plates 15mm apart for an electric field of 750 volts per meter?
By substituting the values into the formula, the potential difference required is calculated as 11.25 volts to achieve the specified electric field strength.
