Do Now (11/5/13) Determine if the circuit is in series or parallel and then solve for the Equivalent Resistances for each of the circuit diagrams: 1) 2) 3)

Do Now (11/5/13) Using the handout on your table Determine if the circuit is in series or parallel Solve for the Equivalent Resistances for each of the circuit diagrams.

Simple Circuits aren’t very useful in the real world. Let’s try something more complex Is this circuit in Series or Parallel?

1) Draw a diagram in a format that makes sense to you!!! Note Sheet 1) Draw a diagram in a format that makes sense to you!!! Format 1 Format 2

1) Draw a diagram in a format that makes sense to you!!! Note Sheet 1) Draw a diagram in a format that makes sense to you!!!

2) Determine which resistors are in series or parallel. Note Sheet 2) Determine which resistors are in series or parallel. Series R1 and R234 and R56 R2 and R3 Parallel R23 and R4 R5 and R6

3) Simplify any resistors in parallel into one equivalent resistor. Note Sheet 3) Simplify any resistors in parallel into one equivalent resistor. Solve for Parallel: R23 and R4 First we solve for R23 R23 = R2+R3 3Ω+2Ω = 5Ω Now we can solve for R234 ⅕ + ⅕ = 1/R234 R234 = 2.5Ω Next we can solve for R56 1/10 + 1/15 = 1/R56 R56 = 6Ω

Note Sheet 4) All resistors should now be in series. Find Req for this series circuit. Easy Math!!! Req= R1 + R234 + R56 Req= 28.5 Ω

5) Your circuit should now be one single resistor and a battery! Note Sheet 5) Your circuit should now be one single resistor and a battery!
