Home Made Circuits and Schematics

A series circuit is a circuit that has only one path for current flow. In parallel circuits different components are connected on different branches of the wire. If you follow the circuit diagram from two identical light bulbs connected in series Circuit diagrams show the electrical connections of a circuit. A single circuit diagram can be drawn many ways Slide 8 - A. In which of the following circuits will the bulb light?B. Draw a circuit diagram for the four arrangements of a battery, bulb This gizmo inspired me to design a distinct USB LED night light with battery backup. Fig. 1: Typical USB LED bulb Fig. 2: SMD LED used in a USB LED bulb Circuit diagram of the USB LED night light is shown in Fig. 3. It is built around USB A-type connector How does an electrical circuit make a light bulb light? USE DIAGRAM AS A SUMMARY! (see Kate Sillman: kas132@psu.edu) Use inquiry to answer the essential questions Predict and test configurations of a battery, bulb, and wire that will make the complete Now test your diagram by creating it in the PhET simulation Looking at the circuits on the back of your Ohm’s Law notes, which circuit do you think will make the light bulbs shine brightest? (write “BRIGHTEST”) Why do you think so? To avoid shock when handling a bulb in a fixture, turn off the switch before touching the bulb. If a light does not work after a bulb is replaced, check to see whether the circuit breaker the socket is faulty. Diagram: Use voltage tester to check .

Students will diagram the inside structure of a light bulb and will trace the flow of electricity through the light bulb as part of a simple circuit. This activity could be used in your classroom (Grades 3-6) at the introductory level of simple circuits. This light bulb is measured on dim-abilty, and interesting parameters are put together in one graph, as function of the mechanical dim position. An interesting graph is the light diagram dimmer (type K8064) is a circuit that uses an analog voltage So I have chosen not to use the 6.5W versions of the GE bulbs. The resulting circuit Reference the diagram above. Note that the current that flows through each of the chip LEDs in turn flows through the fairy light string where the current is divided up 3. Students build a simple circuit to light a bulb with the help of a diagram and demonstration. Tell the class they will now build a closed simple circuit to light a bulb. Show the class the separate pieces they will use: a D cell battery; the holder for .
