2. MIXED CIRCUITS

3. R 1 =16  R 2 = 16  R 4 =32  R 3 = 32  120V Analyze the circuit: A) Calculate R total B) Calculate the current through each resistor. C) Calculate the voltage through each resistor. Parallel:

4. 16  88 120V Series: R 1-234 =16+8 R 1234 =24

5. Make a chart. Include all the resistors including any intermediate equivalent resistances and the total resistance. Then label on the chart, what values will be the same. 16  32  120V RIV 116 2 332 4 2348 123424120 Overall total voltage come from the battery

6. Make chart: 16  32  120V RIV 116 2 332 4 2348 123424120 These are in parallel so their voltage is the same along with the total voltage All these numbers will be the same.

7. Make chart: 16  120V RIV 116 2 332 4 2348 123424120 These are in series so their current is the same along with the total current All these numbers will be the same. 88

8. Fill out the chart with V=IR RIV 116580 2162.540 3321.2540 4321.2540 2348540 1234245120 V = IR 120 = I (24) I = 5 A V = IR V = (5) (8) V = 40 V V = IR 40 = I (16) I = 2.5 A V = IR V = (5) (16) V = 80 V V = IR 40 = I (32) I = 1.25 A

9. 24  120V I=V/R I=120v/24  I=5 amps 5amps Another way to do the problem (without the chart)
