What are the 3 equations for power?

P = ΔV2 / R We now have three equations for electrical power, with two derived from the first using the Ohm's law equation. These equations are often used in problems involving the computation of power from known values of electric potential difference (ΔV), current (I), and resistance (R).

What is the formula for joules?

In words: Work is equal to the force that is exerted times the distance over which it is exerted. In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.

What is efficiency equation?

Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output ("product") produced per the amount C ("cost") of resources consumed.

How do you calculate output?

Total output can be measured two ways: as the sum of the values of final goods and services produced and as the sum of values added at each stage of production. GDP plus net income received from other countries equals GNP. GNP is the measure of output typically used to compare incomes generated by different economies.

What is the output method?

The output approach focuses on finding the total output of a nation by directly finding the total value of all goods and services a nation produces. ... The expenditure approach is basically an output accounting method.

What is total output?

In economics, total output refers to the amount of final products created in a country.

What is lost output?

And, although it is hardly ever mentioned, unemployment also means a tremendous loss of potential output. ... In plain language, jobless workers and unused capacity do not turn out goods and services that could be used to raise living standards.

Is GDP a output?

Economic output is sometimes referred to as gross output or simply output. As stated before, economic output is different from GDP. Gross domestic product is a measure of “value added” at the national level. ... Economic output measures the value of all sales of goods and services.

How output of a country is measured?

The size of a nation's overall economy is typically measured by its gross domestic product, or GDP, which is the value of all final goods and services produced within a country in a given year.

Is national income and GDP same?

GDP (Gross Domestic Product) is a measure of (national income = national output = national expenditure) produced in a particular country. ... GNI (Gross National Income) = (similar to GNP) includes the value of all goods and services produced by nationals – whether in the country or not.

What are the four components of GDP?

The four components of gross domestic product are personal consumption, business investment, government spending, and net exports. 1 That tells you what a country is good at producing. GDP is the country's total economic output for each year.

What output means?

Output is defined as the act of producing something, the amount of something that is produced or the process in which something is delivered. An example of output is the electricity produced by a power plant. An example of output is producing 1,000 cases of a product.

What is output example?

1. Any information that is processed by and sent out from a computer or other electronic device is considered output. An example of output is anything viewed on your computer monitor screen, such as the words you type on your keyboard.

What is daily output?

Daily output represents an average figure, which will vary with job conditions. Daily output is measured in the units specified in the unit column.

What is input and output?

An input is data that a computer receives. An output is data that a computer sends. Computers only work with digital information. Any input that a computer receives must be digitised.

What are 3 input devices?

Computer - Input Devices

• Keyboard.
• Mouse.
• Joy Stick.
• Light pen.
• Track Ball.
• Scanner.
• Graphic Tablet.
• Microphone.

Is a scanner input or output?

Why is a scanner an input device? A computer scanner is a digitizer, which is a type of input device. ... A scanner is only able to send information to the computer and cannot receive information from the computer like a printer (which is an output device).

What is input and output examples?

For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices. Devices for communication between computers, such as modems and network cards, typically perform both input and output operations.

What are the 10 examples of input devices?

10 Examples of Input Devices

• Keyboard.
• Mouse.
• Touchpad.
• Scanner.
• Digital Camera.
• Microphone.
• Joystick.
• Graphic Tablet.

Is speakers input or output?

Are speakers/studio monitors input or output devices? When speakers are connected to a computer (laptop, smartphone, etc), the computer outputs information to be received by the speakers. This means that speakers, monitors, and loudspeakers are, by definition, output devices.

What is input and output design?

Input Design In an information system, input is the raw data that is processed to produce output. During the input design, the developers must consider the input devices such as PC, MICR, OMR, etc. Therefore, the quality of system input determines the quality of system output.

What is a design output?

Design outputs are the results of a design effort at each design phase and at the end of the total design effort. • Establish and maintain procedures for Design Output: – Define and document design output in terms that allow an adequate evaluation of conformance to design input.

What is input and output port?

(1) (Input/Output port) An I/O port is a socket on a computer that a cable is plugged into. The port connects the CPU to a peripheral device via a hardware interface or to the network via a network interface.

What are the tools of system analysis?

Tools and Techniques of System Analysis:

• Grid Charts: Grid charts are used to represent the relationship between two sets of factors in a tabular method. ...
• System Flow Chart: ...
• Decision Tree: ...
• Simulation: ...
• Decision Tables:

What is system analysis example?

Examples of systems analysis might be making a change to some computer code to achieve a task, fixing a faulty air-conditioning system, or analyzing the routines in your life to stop a mistake from happening.
