1. Solving circuit problems Finding Equivalent Resistance

2. The Circuit

5. Finding the Eq. Res. Of this Circuit Start with these resistors in series. Series: R = R1 +R2 R = 4 + 5 R=9 ohm

6. Parallel: 1/R = 1/R1 + 1/R2 1/R = 1/5 + 1/9 1/R = .311 R = 3.21 ohm

7. Parallel: 1/R = 1/R1 + 1/R2 1/R = 1/7 +1/6 1/R = .3095 R = 3.23 ohm

8. Series: R = R1 + R2 + R3 R = 3.21 + 8 + 3.23 R = 14.44 ohm

9. Final Equivalent Resistance
