Yes, calculated di/dt from 10.25ms in increments to 10.001ms and was presented with 30A/s every time so took that to prove that 10ms would equal 30A/s too.
Excellent, thank you ever so much. I know I was on the right lines, just needed pointing in the right direction.
Just to clarify, is the differentiation I have included enough to cover that part of the question would you think?
Thank you for your responses, maybe a mod could move the question elsewhere if this is not the correct place?
As for answering the question in your reply...
I am an idiot its official! Schoolboy error!
The graph is labelled in ms, but I was taking the reading on the calculator to be mA/s...
Homework Statement
A coil has self inductance L of 2 Henrys, and a resistance R of 100 Ohms. A DC supply voltage E of 100 volts is applied to the coil.
Show graphically the approximate rate at which the current increases at the moment of switching on (t=0) and after 10ms.
