Question: What is potential difference across the capacitor if the spacing between the plates is 1.20 mm? Express your answer with the appropriate units ReviewI Constants Periodic Table Two 2.90 cm x 2.90 cm plates that form a parallel …
Explanation: Closer spacing results in a greater field force (voltage across the capacitor divided by the distance between the plates), which results in a greater field flux (charge collected on the plates) for any given voltage applied across the plates.
As distance between two capacitor plates decreases, capacitance increases - given that the dielectric and area of the capacitor plates remain the same. So, why does this occur? As distance between two capacitor plates decreases, capacitance increases - given that the dielectric and area of the capacitor plates remain the same.
Explanation: Larger plate area results in more field flux (charge collected on the plates) for a given field force (voltage across the plates). PLATE SPACING: All other factors being equal, further plate spacing gives less capacitance; closer plate spacing gives greater capacitance.
No, there is no universal lower limit as it depends on the specific materials and design of the capacitor. Different types of capacitors may have different lower limits of separation based on their intended use and construction. 4. Can the lower limit of separation between capacitor plates be exceeded?
In summary, the conversation discusses the potential for loss in a parallel plate capacitor as the distance between the plates decreases. This loss is primarily due to the resistance of the metal plates themselves and can be seen as a decrease in the capacitor's ability to store energy.
As Capacitance C = q/V, C varies with q if V remains the same (connected to a fixed potential elec source). So, with decreased distance q increases, and so C increases. Remember, that for any parallel plate capacitor V is not affected by distance, because: V = W/q (work done per unit charge in bringing it from on plate to the other) and W = F x d
