We will use Gauss''s Law to calculate the magnitude of the electric field between the two plates, far away from the edges. We can imagine a Gaussian surface Σ as shown in Figure 9.That is, Σ is the surface of a small rectangular parallelepiped, half of which lies outside the capacitor, and whose base faces are parallel to the plates. ...

Graphs showing the change of voltage with time are the same shape. Since V = Q/C, it follows that the only difference between a charge–time graph and a voltage–time graph is the label and scale on the y-axis. These graphs show the charge on the capacitor
Capacitor Charge Time
Capacitor charging time can be defined as the time taken to charge the capacitor, through the resistor, from an initial charge level of zero voltage to 63.2% of the …
