Answer and Explanation: To calculate 2 to the 10th power, you need to multiply 2 by itself 10 times. That would look like this: 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2.

Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower. One horsepower is the amount of work a horse can do in 1 minute, which equals 745 watts of power.

To add or subtract with powers, both the variables and the exponents of the variables must be the same. You perform the required operations on the coefficients, leaving the variable and exponent as they are.

In statistics, a power law is a functional relationship between two quantities, where a relative change in one quantity results in a proportional relative change in the other quantity, independent of the initial size of those quantities: one quantity varies as a power of another.

Power is the rate at which energy is transferred. It is not energy but is often confused with energy. The watt is the most commonly used unit of measure for power.

The base B represents the number you multiply and the exponent "x" tells you how many times you multiply the base, and you write it as "B^ x." For example, 8^3 is 8X8X8=512 where "8" is the base, "3" is the exponent and the whole expression is the power.

The current is equal to the electromotive force of the source divided by the total circuit resistance. Power. Power (P) is a measure of the rate at which energy is delivered or used by a circuit element. Voltage sources deliver power, while resistors use power (by dissipating it as heat).

Power Triangle and Power Factor Summary As these three elements are represented by a “right-angled triangle”, their relationship can be defined as: S2 = P2 + Q2, where: P is the real power in watts (W), Q is the reactive power in volt-amperes reactive (VAr) and S is the apparent power in volt-amperes (VA).

Work done = Energy transferred. W = E. Power = Energy ÷ Time. P = E ÷ t.
1137695
Determine the time in which the work will be done. Here, we can take t = 60 s . Power is equal to work divided by time. In this example, P = 9000 J /60 s = 150 W .

["The number of watts is equal to amps multiplied by volts. That's it! ... ", 'For example, if the current is 3 amps (3A) and the voltage is 110V, you multiply 3 by 110, to get 330W (watts). The formula is P=3A X 110V = 330 W (with P standing for power).', 'This is why watts are sometimes called volt-amps.']

Power is the product of Voltage and Current, “Amps ——- Power = Volts X Amps. Power, W = V^2/R, where R is the resistance. It is a directly proportional relationship. Why does power depend on voltage and current?

Electric Horsepower to Kilowatts Since one electric horsepower is equal to 0.746 kilowatts, the formula to find kilowatts is to multiply electric horsepower by 0.746.

The formula for electrical power is P = I \times E. "Power (in watts) equals Current (in amperes) multiplied by Potential Energy (in volts)." How much power is being used in a circuit when the applied voltage is 12 volts DC and the current is 2.5 amperes?
1271037
Power is measured in Joules per second or Watts. Power P is the time derivative of Work W, P= dW/dt. Work can be defined as transfer of energy. In physics we say that work is done on an object when you transfer energy to that object.
