How do you find the voltage at a point in a circuit with respect to a negative voltage?
First of all, 'voltage' means potential difference -and you cannot have a potential difference 'at a point'. Similarly, you cannot have a 'negative' potential difference, so it doesn't make sense to talk about a 'negative voltage'.
Your question, therefore, should read: 'How do you find the potential at a point in a circuit with respect to a negative potential?'
The answer is that you simply connect a voltmeter between the two points. The reading will give you the value of the potential. If it reads upscale, then it'll be positive; if it reads downscale, then it will be negative (i.e. even more negative tan the reference potential).

What is The meaning of Voltage 'V ab' is the voltage at?
V ab is the voltage between two nodes of the circuit. See also Kirchoff's Voltage Law. WHILE CORRECT IT REALY MEANS POINT a to point b in a circuit.
How stability is achived in voltage divider biasing?
A: A transistor needs to be biased at a point whereby it is in a linear point with respect to the load otherwise it can give an output that is non linear or clipping. so with the proper bias the circuit is stable or useful.
What is the formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
Which is the lowest potential point in circuit for nodal analysis?
The negative (or neutral) terminal of the power source.
Is voltage the same as potential?
volt drop and potential difference are effectively the same thing, although the term volt drop is usually used in reference of what voltage has to occur for a diode to conduct, or what volt drop is expected across a long wire etc, potential difference is used to refer to the difference in voltage over a potential divider.
How do use a volt meter?
1. Attach the positive input terminal lead to the positive end of the circuit (or whatever you want to measure the voltage of). 2. Attach the negative input terminal lead to the negative end of the circuit (or whatever you want to measure the voltage of). The voltmeter will turn itself on and measure the difference between the voltage at the first point and the voltage at the second point, telling you how much voltage is traveling between the two points so that is how to use it effectivelly.
What is The meaning of Voltage 'V ab' is the voltage at?
V ab is the voltage between two nodes of the circuit. See also Kirchoff's Voltage Law. WHILE CORRECT IT REALY MEANS POINT a to point b in a circuit.
Can a voltmeter increase voltage?
No, a voltmeter measures voltage in a circuit but cannot increase it. It is a passive device that is simply used to read the voltage at a specific point in the circuit.
DC voltage has no polarity?
A DC voltage must have a polarity, however this polarity is always in reference to some common point and has no meaning on its own, the same with voltage. Usually this common point is the circuit ground, which may or may not be earth ground. Example: A household AA battery has a positive and a negative terminal, the positive terminal is +1.5v in relation to the negative terminal, and the negative terminal is -1.5v to the positive terminal.
What is the definition of grounding as in electricity?
It is where a point in a circuit is at zero voltage.
Why are you going for different type of biasing the transistor?
In each of the biasing circuit ,there are variations in Q-point (undesirable)with respect to the temperature. The voltage divider bias serves a better way to minimize the change in Q-point.
How can a voltmeter be connected in parallel to a circuit to measure the voltage across a specific component?
To measure the voltage across a specific component in a circuit using a voltmeter, you would connect the voltmeter in parallel with the component. This means connecting the positive lead of the voltmeter to the point before the component and the negative lead to the point after the component. This allows the voltmeter to measure the voltage difference across the component accurately.
Rectifier How do you change the 2 arrows direction in the circuit to make it positive or negative In Bridge?
A: Actually there is no changing of diodes required to get negative voltage out put the two cathode to ground if you have a load the voltage across will be negative. Electrons only flow in one direction where the measurement point are located across the load makes positive or negative.
How to check for voltage in a circuit?
To check for voltage in a circuit, use a multimeter set to the voltage measurement setting. Connect the black probe to the ground and the red probe to the point where you want to measure the voltage. The multimeter will display the voltage reading.
Is gold used in circuit breakers?
Certainly not in the case of high-voltage circuit breakers. Probably not in low-voltage circuit breakers, as copper is a better conductor and has a higher melting point.
How stability is achived in voltage divider biasing?
A: A transistor needs to be biased at a point whereby it is in a linear point with respect to the load otherwise it can give an output that is non linear or clipping. so with the proper bias the circuit is stable or useful.
Explain how positive and negative voltages can exist at the same time in a circuit but with only one voltage source?
Voltages are relative. You could, for example, build a simple resistor voltage divider with two resistors and choose the middle point as ground. You would have minus and plus voltages relative to that point then.It is also possible to generate minus voltage (relative to voltage source) with more complex circuitry from a single source. The circuit is called a charge pump.AnswerPositive voltage exists between the power source, and the load (Load being whatever device is being powered). Negative voltage exists between the load and the ground, or negative terminal.AnswerYour question (and the two answers, above) confuses potential difference with potential. 'Voltage' is synonymous with 'potential difference', not 'potential'.The two answers, above, are each describing 'potential', not 'voltage'. There is no such thing as a 'positive' or 'negative' voltage in the 'charge' sense. Voltages are absolute, whereas potentials are relative. So, if one point has a potential of +10 V with respect to, say, earth, and a second point has a potential of -15 V, then the voltage (potential difference) between them is 25 V (no sign!).We can, on the other hand, apply signs to voltages if those signs are used to describe 'sense' or 'direction' in which a voltage is acting. For example, if two batteries are wired in opposition, we can say that the second voltage is acting a 'negative' sense to the first voltage.We do this when we apply Kirchhoff's Voltage Law to a series circuit, when we write an expression such as: V1 +V2 -V3 = 0In the above equation, we are saying that voltages V1 and V2 are acting in one direction, while voltage V3 is acting in the opposite direction.
