Chapter 10 - Electrical Circuits

1. 10.3 Analysing Circuits

   • V = IR
   • P = IV
   • V = W/Q
   • I = Q/t

2. 10.5 Potential Divider Circuits

3. 10.2 Combining resistors

   • Parallel
     • Total resistance is the sum of all the inverses of the resistors
     • 1/R = 1/R1 + 1/R2 + 1/R3
   • Series
     • Total resistance is the sum of all the resistors
     • R = R1 + R2 + R3

4. 10.4 Internal Resistance

   • All wires/components have resistance
   • Lost volts = IR

5. 10.1 Kirchoff's Laws and circuits

   • ΣI(in) = ΣI(out)
     • Charge is conserved
   • ΣƐ = ΣV
     • Energy is conserved

6. 10.6 Sensing circuits
