How do you calculate higher power?
What is a higher power in math? more The power (or exponent) of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number.
What is the efficiency formula? 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.
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 power of a number?
A power is the product of multiplying a number by itself. Usually, a power is represented with a base number and an exponent. The base number tells what number is being multiplied. The exponent, a small number written above and to the right of the base number, tells how many times the base number is being multiplied.
What is 4 written as a power?
In arithmetic and algebra, the fourth power of a number n is the result of multiplying four instances of n together. So: n4 = n × n × n × n.
How do you compare two numbers with different powers?
Write them as numbers between 1 and 10, times a power of ten. Write each power of ten as an exponential expression with the exponent indicating the number of zeros to use. Compare the numbers. The number with the higher power of ten — the larger exponent — is the larger number.
What is the power of two in math?
A power of two is a number of the form 2n where n is an integer, that is, the result of exponentiation with number two as the base and integer n as the exponent. Written in binary, a power of two always has the form 100000 or 0.00 001, just like a power of 10 in the decimal system.

What are the efficiency ratio?
An efficiency ratio measures a company’s ability to use its assets to generate income. Some common efficiency ratios are accounts receivable turnover, fixed asset turnover, sales to inventory, sales to net working capital, accounts payable to sales and stock turnover ratio.
What is the formula for efficiency at full load?
Then the efficiency of transformer can be written as : Where, x2Pcufl = copper loss(Pcu) at any loading x% of full load.
What is current formula?
The relationship between current and resistance in an electric circuit. Current is usually denoted by the symbol I. Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm’s law is I = V/R.
How many kWh per day is normal?
According to the EIA, in 2017, the average annual electricity consumption for a U.S. residential home customer was 10,399 kilowatt hours (kWh), an average of 867 kWh per month. That means the average household electricity consumption kWh per day is 28.9 kWh (867 kWh / 30 days).
What is voltage drop formula?

How do you tell if a number is a power of 4?
A simple method is to take log of the given number on base 4, and if we get an integer then number is power of 4. 2. Another solution is to keep dividing the number by 4, i.e, do n = n/4 iteratively. In any iteration, if n%4 becomes non-zero and n is not 1 then n is not a power of 4, otherwise n is a power of 4.
