Why is Voltage b/w 220 & 330 Olm Resistors 0V?

Click For Summary
SUMMARY

The voltage between the 220 ohm resistor and the 330 ohm resistor in a series circuit is 0V due to the presence of a 0 ohm conductor connecting them. The current flowing through the circuit is calculated as 9.8 mA, derived from the total resistance of 1020 ohms with a 10V source. The voltage across the 220 ohm resistor is 2.157V, and across the 330 ohm resistor, it is 3.234V. Since there is no potential difference across the 0 ohm conductor, the voltage measured between these two resistors is zero.

ok the question I have is why is the voltage between the 220 olm resistor and the 330 olm resistor 0 V.

All resistors in the image are in series so Is=I1=I2=I3

Is = 10/1020 (v/olm) = .0098 or 9.8 mA

V(subscript220)= 220*9.8 mA = 2.157 V (this is the voltage between the DC source and the 220 olm resistor)

V(subscript330) = 330 * 9.8 mA = 3.234 V (this is the voltage between the 330 olm and the 470 olm resistor)

V(subscript470) = 470 * 9.8 mA = 4.606 ( I have to add 3.234 to 4.606 to find the voltage between the DC source and 470 which is 7.84 V)

I am taking the ground up above the the 330 olm resistor.

Ok now I am not sure but I think the reason why the voltage across the 220 to the 330 olm resistor is zero is because I have to make a open circuit in that area which means that no current is actually passing through the wire since current takes the path of least resistance.

be careful how you word your question!
the answer to this question is that you are measuring the voltage on a 0 ohm conductor between r220 & r330
