1)Are the electrical wall outets in your home wired in series of parallel? Explain how you know.2)How do you think the current (I) compares for each of the 3 circuits you built? Is it the same or different? Why? (In class we built a circuit with 2 batteries and a light bulb, then we added another so that we have 2 light bulbs and then another to have 3 light bulbs[those are the 3 circuits])Thanks for all the help!
1: Household outlets are wired in parallel but in a manner similar to series. This means the wires go to each box but at the connection point is the wire to the next box thereby allowing current to flow past any non used outlet. 2: Current would be the increased for each bulb added to the circuit by the amount of power required by the bulb. 3: Like the old christmas light strings you have to unscrew each bulb and replace with a good bulb until you find the bad bulb. Note that in a series circuit when a device fails the entire circuit has no electron flow as the circuit is broken. 4: In a parallel circuit the burnt out light is the only one not lit when power applied to circuit. In a parallel circuit the wiring is connected so that electron flow can bypass any device whether it is on or not or works or not. Therefore each outlet/socket works independent of the others.
1)Parallel. If they were in series, every time you turned a light on the existing ones would get dimmer and dimmer. 2) Depends if the bulbs were added in series or parallel with the 1st. If in series, the current would drop because you're adding the resistance of each successive bulb. If in parallel, it would increase (Net resistance of R's in parallel is always less that the single R). 3) In series they'd all go out. Check the voltage across each bulb. The one with the higest voltage is burned out. 4)All would light up but the bad one
1 Parallel 1B because they have all the same voltage, in series the voltages add up 3, by replacing one after the other or testing with an Ohmmeter 4 the burnt out one would be extinguished if the others are ON Anita
