Question

1. A circuit that contains one battery, two switches (labeled S, and S2) and two lamps (labeled Li and L2) is to be designed so that it does the following: 1) If only S is closed, nothing will happen. 2) If only S2 is closed, only L2 will light. 3) If both switches are closed, both lamps will light. Below are five design attempts at this circuit. In each of the five designs, determine which of the circuit(s), if any, meet all three of the criteria listed above. Fill in the table below with a "Yes" or "No." L2 Circuit: Criterionl Satisfied? Criterion2 Satisfied? Criterion 3 Satisfied? 2. For each of the cases in Question 1 in which the answer is, "No," specifically state what actually does happen in the circuit. 3. Is your home wired in series or parallel? How do you know? What about an automobile headlight? How do you know? What about "bargain" holiday light strings? Again, how do you know?

Please fill in table below and answer question 2+3. Thank you very much and I hope you have a great day!

Answer 1

1

circuit	A	B	C	D	E
Criterion1	yes	no	no	yes	no
Criterion2	yes	yes	yes	no	no
Criterion3	yes	no	yes	no	yes

2   A1 - circuit A ,criterion 1

   B1 - l1 and l2 in series with battery

   B3 - l1 is shorted

   C1 - l1 connected to battery

   D2 - l1 and l2 in parllel with battery

   D3 - l1 is shorted

   E1 - circuit is open

   E2 - circuit is open

3 the home is wired in parllel otherwise if one of the appliances is shorted or tripped all the appliances in the house will not work

Auto headlights are wired in parallel. Then when one burns out, the other remains lit.

holiday/christmas lights are wired in series because if one of the led lights is removed all of them would go off suggesting a series connection
