Hello,

I am solving a dielectric materials assignment to derive the equation for the growth of current in a gap stressed with the high electric field. The equation is as follows:

The equation combines the anode, cathode and attachment process as shown below:

I have derived the two equations with

I have referred to the following course books but unable to find any guidance as both mention direct results.

I will appreciate any help from this forum. Please, this is my first post here

**α and η**&**α and ϒ**processes combined. But when I start to derive the final equation for**η and ϒ**I get stuck in the start as I am unsure of how to add the currents to achieve the final equation.I have referred to the following course books but unable to find any guidance as both mention direct results.
