DAY 170
Video lecture for today: https://youtu.be/zNhqizky9e4
ESSENTIAL QUESTION: How can we build a motor out of magnets, wire, and a battery?
Goals: SWBAT...
1. Solve Ohm's Law V I R related problems
2. Identify circuit schematic components
3. draw simple circuits
4. answer basic questions about magnetism
WARM-UP (4min)
1. define "schematic" a simplified drawing which uses symbols to explain how something works
2. Solve:
a. what is the resistance of an electric frying pan that draws 12 amperes of current when connected to a 120 volt circuit?
b. How much current is drawn by a lamp that has a resistance of 100 ohms when a voltage of 50 volts is impressed across it?
CLASSWORK
1. 170A: Ohm's Law Practice
On paper, you'll use the GUESS method to solve 8 problems, and check your skills with calculating voltage, current, and resistance
2. 170B: Circuit Schematic Practice
On paper, you'll draw a circuit diagram and practice labeling the components.
