Most of us have tried at one point to understand a little about electronics - even if it’s only to replace the plug on an old lamp.
But do you really know your ACs from your DCs?
Our electronics quiz will challenge your school-level electronics knowledge, with questions on everything from units of measurements to resistor colour codes.
The 15-question multiple choice quiz starts off pretty easily, with some pretty obvious questions most people should be able to have a good guess at.
But as you go on, it gets trickier and trickier.
Try your luck below to see if you’re switched on - or just a dim bulb!
