2) three resistors listed as 22k 47k 47k

measured 21.5k 44.4k 42.2k

CALCULATED SUM RESISTANCE 22k+47k+47k=116k

MEASURED SUM RESISTANCE: 114.0k

3)

three resistors listed as 22k 47k 47k

measured 21.5k 44.4k 42.2k

CALCULATED RESISTANCE: 1/(1/42.2+1/44.4+1/21.5)=10.78 ohm

MEASURED RESISTANCE: 11.21 ohm

4)

STATED: 47k, 47k

MEASUReD RESISTANCE: 44.4k , 42.2K

CALCULATED 44.4/(44.4+42.2)*9.56=4.90 v

MEASURED 4.77 v

5)

three resistors listed as 22k 47k 47k

measured 21.5k 46.0k 48.2k

CALCULATION: (46*21.5)/(46+21.5)+48.2+21.69+1/(1/21.55+1/45.96+1/21.56)=93.24 ohm

MEASURED:91.7 ohm

6)

CALCULATION: 21.69/91.7*9.56= 2.26v

MEASURED:2.26 v

7)

MEASURED RESISTANCe

R1 21.5 ohm
R2 21.69 ohm

R3 21.56 ohm

CALCULATED:

v1 21.5/(21.5+21.69+21.56)*9.56=3.17V

v2 21.69/(21.5+21.69+21.56)*9.56=3.2V

v3 21.56/(21.5+21.69+21.56)*9.56=3.18 V

MEASURED voltage:

V1 3.15 v

V2 3.19v

V3 3.18v

HELL all of this is accurate

troubleshoot:

no nothing
