Ohm's Law
Define Voltage and Current:
Voltage is a force used to push current. Current is the flow of electrons.
Define Static:
Still, or not moving
What is the difference between a variable resistor and a fixed resistor?
A variable resistor varies in value while a fixed resistor has a set value that does not change.

28 ohms 5% (26.6 - 29.4 ohms)
12 1/2 + 5 3/4 + 35 1/6
53 5/12
15 + 5(12 - (22 +4))
What's the difference between conventional flow theory and electron flow theory?
Conventional states electrons flow from the most positive point, to the most negative. Electron flow theory is the opposite.
