Name _________________ Date ______________ Class __________ 17-4: Comparison of two Circuits Description Definition How many pathways for the electric charges to flow? Explain. Type of current through each bulb What happens if one bulb burns out in the circuit? Why? What happens to the power as you add more bulbs? Common Uses/Examples of Pros (advantages) Cons (disadvantages) Series Circuit (pg. 496) a circuit in which all parts are connected in a single loop Only one path for charges to follow, so the charges have to move through each part of the circuit DC (one way) Parallel Circuit (pg. 497) a circuit in which loads are connected side by side Wired in parallel so there is more than one path on which charges can travel. AC (alternating) If one light bulb burns out, there is a break in the circuit. None of the light bulbs in the circuit would light. If one load is broken or missing, charges will still run through the other branches. So, the loads on those branches will keep working. If you add more light bulbs, the resistance of the whole circuit would go up and the current would drop. Therefore, all of the bulbs would be dimmer. (pg. 496) Each bulb glows at full brightness, the bulbs do not use the same current, just the same voltage from the battery. Burglar alarms. If any part of the circuit in a burglar alarm fails, there will be no current in the system. The lack of current signals that a problem exists, and the alarm will sound. Let’s you know when there is a problem in the circuit. When one thing on the circuit goes out, everything goes out. (Refrigerator, lamp, etc.) Buildings, homes: each appliance has its own current and/or switch If one thing on the circuit blows out, you can still use the other appliances on the circuit. ? Two wires, two sides parallel to each other. Diagram Name _________________ Description Definition How many pathways for the electric charges to flow? Explain.
