A parallel plate capacitor has a charge of 1.5 × 10 − 6 C and dimensions of 5 cm by 5 cm. Determine the magnitude of the electric field between the plates. Step 1: Determine the charge on each plate of the capacitor. From the question we can say that Q = 1.5 × 10 − 6 C. Step 2: Determine the area of each plate of the capacitor.
The area of a plate is calculated with length times width. A = (0.1) (0.2) = 0.02 m 2 Step 3: Use the equation E = Q ε 0 A to determine the electric field inside the capacitor. Plugging in numbers we get E = 3 × 10 − 6 (8.85 × 10 − 12) (0.02) = 1.69 × 10 7 N / C The magnitude of the electric field inside the capacitor plates is 1.69 × 10 7 N / C.
When we find the electric field between the plates of a parallel plate capacitor we assume that the electric field from both plates is E = σ 2ϵ0n.^ E = σ 2 ϵ 0 n. ^ The factor of two in the denominator comes from the fact that there is a surface charge density on both sides of the (very thin) plates.
