Negative voltage is just a voltage that instead of being positive is negative. If you think of a voltage as a large amount of water in a reservoir, with a pipe connecting it to a basin below, the voltage is the movement of the water from the reservoir to the basin. However, a negative voltage is more like a suction from the basin back up to the reservoir.
Anyway, if you connect the black ( - ) lead of a 9V battery to the black lead of another 9V battery, then the connection between the two black wires is at 0V, or Ground, and one of the batteries' leads will be at +9V, and the other will be at -9V. Negative voltages are only really used in complex circuits, such as ones that contain Operational Amplifiers, and in general doesn't matter in hobby and simple electronics.

When measuring voltage how should test probes be connected?
First connect the positive terminal of the voltage line to positive terminal of multimeter and negative to negative terminal of multimeter. Select voltage in multimeter and measure the voltage
Why the graph of reversed biased diode is lies in third quadrant?
-- The definition of 'reverse bias' is anode negative with respect to the cathode, or negative voltage across the diode. That places the graph in negative-x territory. -- The diode simply acts as a resistor. Its unique 'diode' characteristics arise from the fact that its 'resistance' changes with different bias points, but the current through it always has the same polarity as the voltage across it. Therefor . . . -- When the voltage across it is negative, the current through it is also negative. Negative current appears on the graph in negative-y territory. -- Negative-x territory/negative-y territory is the third quadrant.
What is meant by an electromotive force of 12V?
Electromotive force is an old term for voltage.
What is meant by saying that the potential difference between two points is 1v?
Voltage
What does the positive and negative symbols represent in energy source?
Relative charge. (And/or relative voltage.)
What is mean polar?
What is meant by polarity? Answer An electric charge has a polarity of either positive or negative. Also a voltage has a polarity, in that it could be positive or negative, with respect to some other voltage, such as the one at the other end of a battery or electric circuit.
Is percent voltage regulation can be negative?
yes.. voltage regulation can be negative
What is meant by biased clipper?
A biased clipper comes in handy when a small portion of positive or negative half cycles of the signal voltage is to be removed.
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.
How do you get negative voltage from transformer?
The term, 'negative voltage', refers to its direction and has nothing to do with 'negative' in the 'charge' sense. It's used to indicate the direction in which a voltage is acting in relation to another voltage ('positive' if acting in the samedirection; 'negative' if acting in the opposite direction). So your question is confusing: 'negative' in relation to what?
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
Why telephone line has negative voltage?
A negative live voltage is used to prevent electroytic corrosion on the copper wires.
Why does Negative plus Negative equals Positive?
They don't, however a negative multiplied by a negative creates a positive.
What is meant by voltage source inverter what it does?
no
What are mean and variance of negative binomial distribution by conclusion?
what is meant by a negative binomial distribution what is meant by a negative binomial distribution
When measuring voltage how should test probes be connected?
First connect the positive terminal of the voltage line to positive terminal of multimeter and negative to negative terminal of multimeter. Select voltage in multimeter and measure the voltage
Does battery voltage combine when you use more than one?
The voltage adds if you connect in series (positive to negative). It stays the same if in parallel (Positive to Positive and Negative to Negative).
