Conversion from amp, volt to watt, how to calculate

Conversion from amps to watts

How to convert electric current in amp to electric power in watts.
You can calculate watts from amps and volts. You can't convert amps to watts since watts and amps units do not measure the same quantity.

DC amps to watts calculation formula

The power P in watts (W) is equal to the current I in amps (A), times the voltage V in volts (V):
P(W) = I(A) × V(V)
So watts are equal to amps times volts:
watt = amp × volt
or
W = A × V

Example

What is power consumption in watts when the current is 3A and the voltage supply is 110V?
Answer: the power P is equal to current of 3 amps times the voltage of 110 volts.
P = 3A × 110V = 330W

AC single phase amps to watts calculation formula

The real power P in watts (W) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V):
P(W) = PF × I(A) × V(V)
So watts are equal to power factor times amps times volts:
watt = PF × amp × volt
or
W = PF × A × V

Example

What is power consumption in watts when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 110V?
Answer: the power P is equal to power factor of 0.8 times current of 3 amps times voltage of 110 volts.
P = 0.8 × 3A × 110V = 264W

AC three phase amps to watts calculation formula

Watts calculation with line to line voltage

The real power P in watts (W) is equal to square root of 3 times the power factor PF times the phase current I in amps (A), times the  line to line RMS voltage VL-L in volts (V):
P(W) = √3 × PF × I(A) × VL-L(V)
So watts are equal to square root of 3 times power factor PF times amps times volts:
watt = √3 × PF × amp × volt
or
W = √3 × PF × A × V
Example
What is power consumption in watts when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 110V?
Answer: the power P is equal to power factor of  0.8 times current of 3 amps times the voltage of 110 volts.
P = √3 × 0.8 × 3A × 110V = 457W

Watts calculation with line to neutral voltage

The calculation assumes the loads are balanced.
The real power P in watts (W) is equal to 3 times the power factor PF times the phase current Iin amps (A), times the  line to neutral RMS voltage VL-0 in volts (V):
P(W) = 3 × PF × I(A) × VL-0(V)
So watts are equal to 3 times power factor PF times amps times volts:
watt = 3 × PF × amp × volt
or
W = 3 × PF × A × V

Packaging, Labeling, Warranties, and Guarantees

Packaging, Labeling, Warranties, and Guarantees:- Some product packages—such as the Coke bottle and Red Bull can—are world famous. Many marketers have called packaging a fifth P, along with price, product, place, and promotion. Most, however, treat packaging and labeling as an element of product strategy. Warranties and guarantees can also be an important part of the product strategy and often appear on the package. Packaging Packaging includes all the activities of designing and producing the container for a product. Packages might have up to three layers. Cool Water cologne comes in a bottle (primary package) in a cardboard box (secondary package) in a corrugated box (shipping package) containing six dozen bottles in cardboard boxes. The package is the buyer’s first encounter with the product. A good package draws the consumer in and encourages product choice. In effect, they can act as “five-second commercials” for the product. Packaging also affects consumers’ later product e...

Factors influencing Political Behaviour in organizational behaviour

Factors influencing Political Behaviour The  Factors influencing Political Behaviour figure  depicts that there are two factors that influence the political behavior in the organization, individual factors and the organizational factors. Individual factors include certain traits of the individual that are likely to be related to the political behaviours. Employees, who possess high self-monitors, regularly keep check on their performance, and are more sensitive to the social cues. Those who have internal locus of control believe they can control the environment and can easily manipulate things and have a very high need of power. The Machiavellian personality is characterized by the desire to manipulate others and acquire power in the organization. These kinds of employees are more prone to engage in some sort of political behaviors in the organization. Also individual’s high expectation of success fosters political behavior. Organizational Factors also give rise to the...

The Communications Process Models

The Communications Process Models:- Marketers should understand the fundamental elements of effective communications. Two models are useful: a macromodel and a micromodel. MACROMODEL OF THE COMMUNICATIONS PROCESS:- a macromodel with nine key factors in effective communication. Two represent the major parties— sender and receiver. Two represent the major tools—message and media. Four represent major communication functions—encoding, decoding, response, and feedback. The last element in the system is noise, random and competing messages that may interfere with the intended communication.11 Senders must know what audiences they want to reach and what responses they want to get. They must encode their messages so the target audience can decode them. They must transmit the message through media that reach the target audience and develop feedback channels to monitor the responses. The more the sender’s field of experience overlaps that of the receiver, the more effective the me...
