I did a tangent off the curve and worked out the gradient of that :/

I did but I didn't realise I did I/V instead of V/I 😭😭

The curved line for the filament bulb wasn't straight though

The line started off curved, and then went to a constant resistance, however this was only under a certain voltage range.

That question was so horrible. how do u even find the resistance of the resistor???

Im pretty sure the resistance of the resistor was the reverse gradient dV/dI

high pd to accelerate atoms to collide
i referenced the last point to my calculation for the energy of photon , as it is released when dropping from 3.4 to 1.5 so 1.9 ev
