When there is a connection across both the positive and negative voltages.
the DSU converts the binary data pulses it receives from the DTE to the line encoding format required by the network, withing the computer the one bits are positive voltages, and zero bits are not voltages or low level voltages.

In this context, 'negative' and 'positive' are used to indicate the sense, or direction, of the induced voltages, as voltages do not have electric polarity (+ or -). The direction of the voltage induced into a conductor is determined by the direction of that conductor relative to the magnetic field. As the coil rotates, the directions of each side of the coil reverse relative to the field, and the induced voltages reverse too.
The positive and negative supply voltages. Analog amplifiers clip a few volts short of their voltages, so these two supplies are usually 12 volts or more.
It's a power supply with a positive and negative voltage, where one of the voltages tracks the other. For example: the negative voltage tracks the positive. If you regulate the positive to 15v, the negative is going to be -15v. This allows very precise symmetric power.
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.
In Positive logic, we all assume that the more positive (binary) voltage state is One, the less positive voltage state is Zero.Both voltage states could be positive, both could be negative, or they could be opposite polarities.
Yes. By convention, the horizontal line is deflected upward for positive voltages and down for negative. With no input, adjust the line to co-incide with a central line on the graticule. A varying voltage that remains positive will be deflected above the line. A voltage that transits from positive to negative will draw above and below the line.
