No Warm-Up. Sign out your Switch-On! kits and start learning :)
Classwork:
091A & 92B Continued: Advanced Circuits & Components
- What's a switch? What's a resistor? Capacitor? Transistor?
- You likely know some of these terms, but not all.
- We'll spend our last four days of class using, and learning about, the major components of circuit.
- Things you'll do:
- create real circuits that make lights flash, make sounds, etc.
- diagram circuits using symbols
- research circuit components, and describe their function
- discuss what you've learned
- Assignment: Learn about circuits components, and how they work, by completing "Switch On!" mini-labs
- Assessment: You'll create two documents, both of which will be multiple pages long:
- 1. Lab Summary Doc (3 columns) : Mini-Lab Title; Circuit Diagram (AKA schematic); Concepts Illustrated in Lab
- 2. Circuit Components (4 columns): Component Name; Symbol; Function (what it does); How Does It Work?
- Groups: 3-5 students per kit, depending on class size
HOMEWORK (due Wednesday):

Questions:
- Define the term "Resistance" (here's a photo of a resistor: http://usbflashrecovery.com/flash-drive-whats-inside/)
- Write the equation for resistance, label each of the variables, and list the symbol (unit) for resistance
- Copy the graph of V vs I for an ohmic material
- Oop! Mr. P said that one of the equations you already wrote is called Ohm's Law. Put that title next to the appropriate equation.
- Copy the graph of V vs I for a non-ohmic material
- The non-ohmic graph is non-linear. Think about what that means... What happens to the current as the voltage increases?
- Draw the diagram of the battery/lamp circuit, and the graph which goes along with it.
- As PEele passes through the lamp, it gets converted into....what?
- Watt (get it?) equation do we already know for power?
- Copy & follow along as Mr. P derives the three equations for electric power. You may need to watch this section a few times to really get the connection between the equations.
- Finally, the dimensions of power are....?
Extra Credit:
1. Complete #31-48 correctly LINK. Draw the diagrams, and use a different color pen or pencil to show the flow of current throughout the ENTIRE CIRCUIT. Due by Wednesday.
2. Other extra credit available this week. Complete "Switch On!" mini-labs #16-40 for extra lab points. Due by June 6th.
Seniors, your finals begin next week. Your review is here: LINK
Non-seniors, your finals begin Friday the 1st. Your review is here: LINK
For both groups, you may bring your equation sheet (AKA Table of Friends) to the exam. You should also bring a calculator, and a pen/pencil. As usual, no phones for calculators.
