Can watt meter negative reading?
Yes. This is usually an indication that either its current coil or its voltage coil has been wired incorrectly.
What is the significance of obtaining a negative reading in testing voltage?
Electric current can flow in one of two directions in a wire; with alternating current, the direction changes continually, back and forth. The use of positive and negative values for voltage gives you a direction for the voltage. If current flowing to the right is positive, then current flowing to the left is negative.============================Answer #2:A negative reading indicates that the point to which the positive probe ofthe voltmeter is connected is at a lower potential than the point to whichthe negative meter probe is connected. It tells nothing about the circuitconditions except in combination with the knowledge of how the meteris connected.
Is percent voltage regulation can be negative?
yes.. voltage regulation can be negative
What is negative 48 volt DC voltage?
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
What is the significance of negative values of voltage and current?
What is the significance of negative values of voltage and current?Negative values show direction and that is the significance
When is it important to make sure to match the polarity of the meter leads to the polarity of the circuit being tested?
This is important when meter cannot display negative values, e.g. it is analogous meter with scale. Most digital meters can display negative values. P.S. I am amateur in elecrtonics.
You are wiring a LED lamp through a transformer you have a polarized plug and you know positive and negative The transformer is marked live and neutral Does live correspond with positive or negative?
LED's are DC voltage. Transformers are AC voltage. There is no positive or negative on AC voltage. You would need a diode to change the AC to DC, then there would be positive and negative voltages.

What is the voltage reading of positive wire in 110V dc?
You should be asking, 'What is the potential reading of a positive wire....?', as 'voltage' means 'potential difference' and you can't have a potential difference on a wire! The positive wire has a potential difference of +110 V with respect to the negative wire.
Does the coil on a1969 Chevy have the same voltage on the plus and - side of the coil when the ingintion is on?
When you take a voltage reading at the coil with ignition on and the ignition points are open you would get the same reading on both + and - .
What would the ohm reading be on a digital meter for a 4500 watt baseboard heater?
To calculate the ohm reading of a 4500-watt baseboard heater, you would need to know the voltage it operates at. You can use the formula Ohms = (Voltage x Voltage) / Watts to find the resistance in ohms. For example, if the heater operates at 240 volts, the ohm reading would be approximately 12.8 ohms.

How to read voltage on a multimeter?
To read voltage on a multimeter, set the dial to the voltage setting, typically labeled as "V." Connect the red probe to the positive terminal and the black probe to the negative terminal of the circuit or component you want to measure. The multimeter will display the voltage reading in volts on the screen.
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).
