Circuits – The Cliff’s Notes (chapter 17.3 and 18.2) Name: _______________________________ Schematic Diagrams: Battery: Resistor: Bulb: Open Switch: Closed Switch: Wires: Water Analogy: Voltage: In DC circuits, supplied by: Current: Resistance: Examples: Circuit Demonstration – understanding what it was about: What did Ms. Brock represent? Explain the difference between the money and the hula hoop analogies and what that has to do with electric circuits. What happened when one person held the hula hoop tighter? What did this represent?: Ohm’s Law: *Note! Ohm’s Law does not hold for all materials! Some materials a “Ohmic” and some are “Non-Ohmic” – only materials that keep their same resistance over all voltages are “Ohmic” Examples with Ohm’s Law: 1. A stove is connected to a 180 – V outlet. If the heating element has a resistance of 18 ohms, calculate the current flowing through it. 2. In order to operate a hairdryer, the current required is 2.5 A. What is its resistance if the voltage supplied is 120V? 3. If the resistance of a refrigerator is 130 ohms and the current is 0.845 A, what is the voltage? Now Try: Practice D, Chapter 17 Series and Parallel Circuits: (Chapter 18.2) Resistors in Series: Resistors in Parallel:
