Resistors

This is a really long confusing unit. We've learned about resistors. In a series, more resistors means more resistance. In parallel, more resistors means less resistance. It's a mathematical thing.

Series: R1 + R2 + R3 = total resistance
Parallel: 1/R1 + 1/R2 +1/R3 = 1/total resistance

See how that works out? We've also been getting into hectic stuff. Scientists are crazy. Anyway, the extra practice and repetition for this class has been really helpful. To sum everything up, in series, current is the same throughout the entire thing, while the voltage of the resistors when added together create the voltage of the source. In parallel, the sum of the current through each resistor is the current from the source, and voltage across each resistor is the same.

Also, to find the I(batt), total voltage must be divided by equivalent resistance.
