Lily’s Shockingly Great Problem

OPENING QUESTIONS:

    • Do you have an effective method of getting through an FRQ?

    • What do you remember about DC circuits?

    • What are some of the general formulae?

    • How do you determine resistance in series vs. in parallel?

    • What happens if a capacitor is in the circuit?

OBJECTIVES:

I will be able to calculate the equivalent resistance of a network of resistors that can be broken down into series and parallel combinations.

I will be able to calculate the voltage, current, and power dissipation for any resistor in such a network of resistors connected to a single power supply.

I will be able to apply Ohm’s law and Kirchhoff's rules to determine a single unknown current, voltage, or resistance.

Write expressions to describe the time dependence of the stored charge or voltage for the capacitor, or of the current or voltage for the resistor.

WORDS FOR TODAY:

Resistor: An object having a designed resistance to the passage of an electric current

Capacitor: Two charged surfaced where electric energy can be stored

Series: Resistors connected in a line, add together

Parallel: Resistors connected across from each other, add opposite reciprocals and reciprocate

TERMS:

CONSTANTS:

FORMULAE:

V=IR (Ohm’s Law)

Units:

V: Voltage (V)

I: Amperes (A)

R: Ohms (Ω)

C: farads (f)

WORK O' THE DAY: 

So, wire we doing this problem? Well, I’m positive that it will be great practice for our current AP test this next May!

Alright, enough with the puns, here’s our problem:
