5: F 4/13, 7: F 4/13Today, we'll first go over the results of your lab, and review the relationship between voltage, current, and resistance, which we call Ohm's Law. We'll also review the general equation for power and the equations for power lost in a resistor. Then, we will start to look at more complex circuits - where circuit elements such as light bulbs are connected in series and parallel. We will observe a demonstration of series and parallel light bulb circuits and qualitatively analyze the effects on the brightness of the bulbs. We will try to determine what is happening in the circuit using our knowledge of voltage, current, and resistance. We'll also learn how to draw schematic diagrams of circuits in order to help us communicate our ideas.Presentation: Light bulbs, Power, and Series & Parallel CircuitsHomework: |
