Finished Paper 43 today,
But I encounter two weird questions for the paper,
1. - Band Theory for Metals, but diagram given have no overlap of conduction band
2. Op-amp, where is the direction of current flowing?
Uncertainty for the graph for Lenz's Law and EMI, how to draw E vs t graph from I vs t?
