If the capacitor is an axial version having leads at both ends of the package, the polarity marking stripe may be accompanied by an arrow that points to the negative lead. For leaded tantalum capacitors the polarity markings indicate the positive lead. A + sign is placed close to the positive lead. When new, a further polarity making may be used because it may be seen that the positive lead is longer than the negative one.
Consider the following parallel plate capacitor made of two plates with equal area $A$ and equal surface charge density $\sigma$: The electric field due to the positive plate is. $$\frac{\sigma}{\epsilon_0}$$. And the magnitude of the electric field due to the negative plate is the same.
