6 FAQs about [Capacitor electrode plate spacing]
How do you find the capacitance of a parallel-plate capacitor?
The electric field between the plates of a parallel-plate capacitor To find the capacitance C, we first need to know the electric field between the plates. A real capacitor is finite in size. Thus, the electric field lines at the edge of the plates are not straight lines, and the field is not contained entirely between the plates.
How does plate spacing affect capacitance?
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.
What happens if a capacitor is closer to a plate?
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.
How does distance affect a parallel plate capacitor?
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 and F = q x E so, V = F x d /q = q x E x d/q V = E x d So, if d (distance) bet plates increases, E (electric field strength) would drecrese and V would remain the same.
