Can Voltage dividers can provide only positive output voltages?

Voltage dividers can provide anything between VCC (the most positive voltage in the circuit) and VSS (the most negative voltage in the circuit). For example, if VCC =0 and VSS = -15, then the output voltage has to be negative.

What are voltage dividers?
Voltage dividers are used in a linear circuit to separate the input voltage into a small portion known as the output voltage. It is commonly used to get a low voltage signal equal to the voltage being measured.
Are the terms voltage limiter and voltage regulator interchangeable?
No. A voltage regulator usually can provide control in both directions (increasing or decreasing voltages). A voltage limiter clamps the voltage to below a specific level.
Why v use ac in home?
It is easy to transform a.c. voltages to any desired voltage very efficiently, and it is also easy to rectify a.c. voltages to provide d.c. voltages. This means that both a.c. loads and d.c. loads can be connected to the a.c. supply.
What is the need for power supplies?
A power supply is needed to transform the line voltage (e.g. 120 VAC 60 Hz, 240 VAC 50 Hz) to the voltage or voltages needed by the equipment (typically DC voltages between 3 VDC to 300 VDC) depending on the operational requirements of the equipment. Some old vacuum tube equipment needed low voltage AC to heat the vacuum tubes, the power supply then also had to provide these voltages (e.g. 6 VAC, 12 VAC). I have seen power supplies as simple as providing just one DC voltage to power supplies as complex as providing 20 to 30 different DC voltages, some positive and some negative with respect to ground.
What is a device that increase or decreases voltage in a power line?
A transformer. A small example is the coil in a motorcar. A transformer, in a power line, only changes voltage in one direction under normal usage. At distribution voltages, about 8360 VAC, the voltage is monitored by a regulator. A regulator either increases or decreases the voltage automatically to insure the desired voltage is steady. This regulated voltage is then fed to Transformers to provide customers with a regulated voltage at the desired voltage.
Can you say which bridge rectifier voltage has the highest out put voltage?
A: NO the power output will be higher. Bridge rectifiers do not provide more voltage output it just add more power by rectifying both positive and negative voltage of the AC input
Which companies provide desk dividers?
Office Partition, home department stores, computer and technology stores, and furniture stores provide them.
Can you use a potential divider for obtaining variable DC supply from a fixed AC supply?
Power supply providing constant D.C. output voltages from variable A.C. input voltagesThe novel power supply for generating a constant d.c. voltage from a variable a.c. voltage supply line, includes a plurality of switch circuits (10, 12) which monitor voltage levels on respective secondary windings (L,M,H) of a power transformer and as voltage levels change, one of the plurality of switch circuits is selected to charge a capacitor (C1) which provides a range of d.c. voltages which are processed to provide the constant d.c. voltage.
What are the voltages that the secondary distribution center can provide to the loads connected to it?
120/208VAC
How many ampere use for 5000watt?
It depends on voltage. You did not provide voltage, nor did you provide resistance from which we could calculate voltage. Please restate the question.
What is a common source for a voltage?
Batteries provide a voltage difference.
What does not provide a voltage difference in a circuit?
Wires do not provide a voltage differenceAnswerAs 'voltage' is synonymous with 'potential difference', you appear to be asking "What does not provide a potential difference difference in a circuit?", which does not make any sense!
