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

In summary, the voltage between the 220 ohm resistor and the 330 ohm resistor is 0 V because all resistors in the circuit are in series, resulting in a total current of 9.8 mA. The voltage between the DC source and the 220 ohm resistor is 2.157 V, while the voltage between the 330 ohm and 470 ohm resistor is 3.234 V. To find the voltage between the DC source and the 470 ohm resistor, we must add 3.234 V and 4.606 V, resulting in 7.84 V. When considering the voltage between the 220 ohm and 330 ohm resistor, we must take the

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 resistence.

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

So basically, the voltage between the 220 olm resistor and the 330 olm resistor is 0 V because there is no current flowing through that section of the circuit. This is because the 330 olm resistor has a higher resistance than the 220 olm resistor, so all of the current is flowing through the 220 olm resistor and none is passing through the 330 olm resistor. Therefore, there is no voltage drop between the two resistors, resulting in a voltage of 0 V.
 

1. Why are 220 and 330 ohm resistors commonly used in electrical circuits?

220 and 330 ohm resistors are commonly used in electrical circuits because they are considered to be standard values that are readily available and can be easily substituted for other resistors. Additionally, these resistors provide a balance between resistance and power handling capabilities.

2. What is the significance of voltage in relation to 220 and 330 ohm resistors?

Voltage is the measure of electric potential difference between two points in a circuit. In the case of 220 and 330 ohm resistors, the voltage is typically between 0V and the supply voltage. This means that the resistors are designed to handle a specific range of voltage in order to regulate the flow of current in a circuit.

3. How does the resistance of 220 and 330 ohm resistors affect the performance of an electrical circuit?

The resistance of a resistor determines the amount of current that can flow through it. In the case of 220 and 330 ohm resistors, their resistance values are relatively low, meaning they allow for a higher flow of current. This can be useful in certain circuits where a higher current is needed.

4. Why is the voltage between 220 and 330 ohm resistors measured at 0V?

The voltage between 220 and 330 ohm resistors is measured at 0V because these resistors are typically used in series with other components in a circuit. This means that the total voltage drop across the resistors is equal to the supply voltage, resulting in a 0V measurement between the resistors.

5. Can 220 and 330 ohm resistors be used interchangeably in a circuit?

Yes, 220 and 330 ohm resistors can be used interchangeably in a circuit as they have similar resistance values and power handling capabilities. However, it is important to note that the specific requirements of a circuit may require one resistor over the other, so it is best to consult a circuit diagram or datasheet before making any substitutions.
