My Estimate
Maximum/Minimum
  1. 714000/646000 ohms Blue, Grey, Yellow, Gold
  2. 10.5/9.5 ohms Brown, Black, Black, Gold
  3. 10100/9900 ohms Brown, Black, Black, Red, Gold
  4. 1575/1425 ohms Brown, Green, Red, Gold
  5. 465000/313500 ohms Orange, Orange, Yellow, Gold
  6. 1050/950 ohms Brown, Black, Red, Gold
Actual Reading
  1. 691000 ohms
  2. 10.5 ohms
  3. 9960 ohms
  4. 1488 ohms
  5. 329000 ohms
  6. 994 ohms
I calculated the resistance of the resistors, I then measured their resistance with my multimeter to confirm my calculations. All of the actual readings were within the tolerances.

R1= 1500 ohms R2= 1000 ohms
In seires I calculated 2500 ohms by adding 1500+1000 together, and when measured it was 2500 ohms.
In parallel I calculated 600 ohms by using the formula 1/RT= 1/R1+1/R2.

When measure it was 600 ohms.

I have demonstrated that parallel circuits have less resistance that seires circuits.

  1. could you please show your calculations for series and parallel resistors
