Explain why

Explanation / Answer

calculation (using measured value of R1, R2,R3 ) in ohm:

R12 = R1 +R2 = 1550 +1000 = 2550 ohms

R23= R2 + R3 = 1000 +1200 = 2200 ohms

R123 = R1 +R2 + R3 = 1550 +1000+1200 = 3750 ohms

calculation of currents is as follows:

1) as V1 = I1 *R1

   2.61 = I1 *1550
   I1 = 2.61/1550 = 1.68 X 10^-3 A    (mA = MILLI AMPERES )
           = 1.68 mA
2) as V2 = I2 *R2

   1.68 = I2 *1000
   I2 = 1.68/1000 = 1.68 X 10^-3 A    (mA = MILLI AMPERES )
           = 1.68 mA
3) as V3 = I3 *R3

   2 = I3 *1200
   I3 = 2/1200 = 1.67 X 10^-3 A    (mA = MILLI AMPERES )
           = 1.67 mA
4) as V123 = I123 *R123

   6.32 = I123 *3750
   I123 =6.32/3750 = 1.68 X 10^-3 A    (mA = MILLI AMPERES )
           = 1.68 mA

I123 =   I total
