How do you calculate total resistance in a series circuit?
RT = R1 + R2 + R3 + ...
100
What is Ohm's Law?
V = I * R
(Voltage equals current times resistance)
100
What 3 things does every circuit NEED?
Pathway, Resistor, Power Source
100
What are the two types of circuits?
Series & Parallel!

Can sound travel through space?
NO!
Sound can't travel through space, so if you talk to someone on the moon, they wouldn't be able to hear you unless there was a way to send sound waves through a medium!

R2 = 231Ω
200
What are the units for Ohms Law?
V = volts
I = Amps
R = Ohms

The Eiffel Tower can grow up to about 6 inches taller in the summer. Why?
It's because the heat makes the iron expand!
