Electronics Quizzes, Questions & Answers

Does the ham radio need some spicy sauce, or does it need backup batteries? How about a bleeder circuit? Oh... you know that it’s not really losing blood, don’t you? Will you be sent to prison for breaking Ohm’s law? OK,enough of those silly questions. Here come the real questions. So, do you know what a RAM is? How does it differ from a ROM? Can you tell the resistance of a resistor just by looking at its color bands? There is actually a mnemonic for that. Do you remember? If you know the answer to most of the questions, then you must be quite the electronic enthusiast.

Watt are you waiting for? Show us how wide your knowledge bandwidth is and take on the electronics challenge.
