 # What are the input and output voltages?

Is a voltage delivered to the circuit, while an input voltage is a system supply voltage. An input voltage is the voltage required to power the system. Output voltage is the receiver component that generates voltage. The predicted load across the load when obtaining energy loss along the load is known as the output voltage. For example, if there is a 100-watt resistor connected between two 110-volt AC sources in parallel, then the output voltage will be 10 volts AC regardless of which source you use for your input.

Input voltage is the term used to describe the voltage that is provided to an electrical device or system. It should not be confused with standard voltage, which is the term used to describe the voltage that is supplied to an electrical device or system. Input voltage can be either direct or alternating current (AC). Alternating current (AC) is the term used to describe the voltage that is provided to an electrical device or system that contains components that require periodic reversal of the polarity of the current being delivered (such as motors, compressors, and generators). Direct current (DC) is the term used to describe the voltage that is provided to an electrical device or system containing components that do not need periodic reversal of the polarity of the current being delivered (such as resistors and capacitors).

Output voltage is the term used to describe the voltage that is generated by an electrical device or system.

## What is the difference between operating voltage and input voltage?

Input voltage is something that you feed from a power source to that equipment in order for it to function. The operating voltage, on the other hand, is connected to the product's capabilities. It signifies that the product can provide the correct output even if the input voltage changes by +/- 5%. As long as the output remains constant, the operating voltage is satisfied.

For example, let's say you have a laptop computer. Its operating voltage is defined by the manufacturer, so look for that value on the packaging or on Microsoft's website. If the operating voltage is 12 volts, then that means the computer will work correctly with either a regular household current of 120 volts or a special current for laptops called "alternate current" (AC) which is approximately 110 volts. If the operating voltage is 6 volts, however, you should not use any more than about 7 volts as there would be no point in wasting energy when you could easily get by with less.

Now, suppose you take this computer on an airplane where they only have 110-volt AC power available instead of the usual 120 volts. Will your computer be able to operate properly with only 110 volts? No, because the operating voltage of most computers is higher than just 110 volts. It may be 125 volts or even 200 volts but never lower than 110 volts!

## What is the output offset voltage?

The DC voltage between two output terminals is measured when the input terminal(s) are grounded (or the output terminal and ground for circuits with one output) and the other terminal is connected to VDD. This test must be done before any operation is performed on the device to ensure that no damage has occurred to the outputs due to manufacturing defects or tampering.

An IC has an internal bias current that flows through all of its internal nodes, including the output nodes. This bias current offsets some of the voltage drops across the rest of the circuit, so even if the output is high impedance, some voltage will appear across it. The amount of this offset voltage depends on how much current the bias source can supply, and how reactive the load is at those frequencies. For example, if the load is a resistor, then it will present about 2 volts across it when the output is high. That's the output offset voltage.

In general, output offset voltage can be divided into two parts: static and dynamic. The former is caused by leakage currents flowing through the output devices when they are not conducting any charge; the later results from noise signals applied to the inputs of the IC causing the output to toggle.

Output offset voltage can have negative effects on circuit performance.

## What are the voltages provided by a power supply?

Voltages measured at standard outputs A power supply unit's positive output voltages are +3.3V, +5V, and +12V. Negative voltages of -5V and -12V, as well as a +5V standby voltage, are also available. The standard voltage levels for interfaces with computers are 3V to 5V for +3.3V and +5V, and 2.8V to 3.6V for the +12V bus.

The term "supply" is used to describe both the voltage itself and the device that produces it. A battery is an example of a supply: It provides a constant voltage source. Batteries are made up of cells which provide several different voltage levels depending on how many are connected together in series or parallel. For example, a 9V battery contains 18 individual cells each producing 1V when connected in series.

Supplies can be divided into two main types: single-supply devices and dual-supply devices. Single-supply devices produce only one voltage level; they cannot provide separate voltage sources for circuits using different parts of the power supply's circuitry. Dual-supply devices produce two distinct voltage levels; they can therefore be split between two circuits requiring different operating voltages.

A voltage regulator is a circuit that produces a constant voltage from an inconsistent source such as a battery or generator.
