Miller’s Combination & Advanced Circuits
Schedule 2019 L3
Circuits Goals - You should be able to…
1. All the basic circuit information we learned last unit is still fair game for this unit too.
2. Determine the value of a given resistor when given the three colors and the color code.
3. Solve combination circuits for current, voltage, resistance, and power.
4. Use Kirchhoff’s Rules to solve circuit problems.
Junction rule (conservation of charge): I IN
I OUT
x
Loop Rule (conservation of energy): VLOOP
0
5. Know how switches are used to turn circuits on and off.
6. Know how switches work in series (Good) and parallel (Bad).
Q
7. Know the definition of Capacitance ( C
)and use the equation so that given two of the three
V
variables you can solve for the third.
8. Explain how capacitors function in a circuit when the circuit is initially connected (like a wire) and after
a very long time (like an infinite resistor) in order to solve circuits involving capacitors.
9. Know the basic shapes of voltage vs. current graphs of circuits with capacitors in them.
10. Know how capacitors add in series and parallel.
11. Understand the term, “short circuit.”
