QUESTION 1

What type of logic gate is created by each of the switch circuits below?

QUESTION 2

Which of the following Diode Logic circuits is an AND gate and which is an OR gate?

QUESTION 3

a) LED stands for ____________ ____________ ______________.

b) A(n) _____________ is an electronics device that allows current to flow through it in only one direction.

c) When considering a diode’s symbol, the side with the straight bar is the _______________ side. This is of course if you want current to flow through the diode.

d) A(n) ______________ is an electronic device that stores electric charge.

e) A(n) ______________ is an electronic device that acts like a switch. It has 3 legs. If a small current flows between the middle leg and one of the outside legs, then, and only then, will the two outside legs be connect and allow for a larger current to flow through.

f) A(n) ________________ is an electronic device that allows us to turn a dial to change the resistance in a circuit. We commonly see such devices as radio volume dials or light switch dimmers.
