thanks heaps in advance!!

just had mine, it was basically semiconductors (diodes), with a graph of voltages and currents aswell as when polarity was reversed (ie the battery put in the wrong way).. also a question on CRO readings at various points in a circuit with a diode and a resistor.

caught a lot of people out, but wasn't too hard..
