ВЭФ 12 (Astrad VEF 12 Project) - including a transistor tutorial

[Crackle]

I think what would be useful here is if somebody asked, what do we know about the current flowing through each part of a series of resistors or bulbs, in a simple circuit. How can we use that to work out the voltage across the 4.7K resistor, and deduce the volts at the collector of the transistor.
