Shock Value B/Circuit Lab C Question Marathon

Nice answer, looks right to me! Yeah writing boolean algebra on here isn't the easiest thing I guess.

I believe digital logic is a new theoretical topic this year, introduced in rule 3.d?

Yup. Boolean logic is new this year, limited to the exam portion of the event.

Sweet!
(I will post the new question tomorrow, its already 10 where I'm at)

Alright, let's try this:
draw/CAD/etc. a Wheatstone bridge. Then state the equation used to find the resistance of an unknown resistor using it.

First you vary resistor 2 until the Galvanometer reads 0 V, then you plug the values into:
Rx=R2/R1*R3

'Tis correct.

I am really sorry it took this long for me to get up a question

Who discovered electromagnetic induction, and describe his/her setup which was used to discover it

My answer is (Click to Show Hidden Text)

Electromagnetic induction was discovered by Michael Faraday. He wrapped two wires around opposite sides of an iron ring. He plugged one wire into a galvanometer and the other one into a battery. When he did so, he saw a transient current.

Correct, your turn
