Measure the currents and potential differences for the parallel circuit shown in page 6. batteries = (Scale: Write an equation relating the 3 currents: round = (Scale: Ilong = (Scale: Write an equation relating the 2 potential differences: AVround = (Scale: AVlong (Scale: For components connected in parallel, the potential difference is (the same/shared), while the current is (the same/shared). Which light bulb has higher resistance? How can you tell? Is this consistent with the answer from the series circuit? Yes No From this exercise and the ones on Page 4, we see that the parallel connection allows multiple appliances to work together, but the total current increases as more appliances are connected. High current through a wire is a fire hazard. That is why we need fuse or jumper in our home, which stops the current if it is too high. Strictly speaking, one cannot say parallel appliances work independently: if you connect too many appliances, total current will be too high, and the jumper will disconnect power to every appliance.Measure the current and potential difference in a parallel circuit. Now connect the 2 bulbs in parallel. See the diagram below. Are both bulbs lit? Yes No round bulb long bulb Unscrew the round bulb. What happens to the long bulb? no light dimmer same brighter Screw the round bulb back. Unscrew the long bulb. What happens to the round bulb? no light dimmer same brighter Based on our experiments on two connections, how should the wiring be done? Compare from two situations below: Light bulbs wired in parallel Light bulbs wired in series Can all light bulbs light up brightly when you want them to? Will turning one light bulb on/off affect the others? As a summary, will you wire your light bulbs in parallel or in series? parallel series In the space below, draw the circuit to obtain the maximum amount of light with 2 batteries and 3 bulbs. Same connection will work for more bulbs, but it may cause a problem (see Page 7). 1118 Circuits (Handout) - 6 Saved: 4/28/23, printed: 4/28/23Step by Step Solution
