**Input and output power**

- Electrical power is calculated by multiplying voltage (in volts) by current (in amps).
- If a transformer is 100% efficient, then the input power will equal the output power.
- V
_{P}is input (primary) voltage. - I
_{p}is input (primary) current. - V
_{s}is output (secondary) voltage.

Another way to measure the capacity of the battery is in Watt-hours (Wh). Wh is calculated by **multiplying the number of Amps with the battery voltage**. For example, a 12V100 (a 12 volt battery with a capacity of 100Ah) has a capacity of 12 x 100 = 1200Wh. A 24V50Ah battery has a capacity of 24 x 50 = 1200Wh.

Power Output means the average rate of electric energy delivery during one Metering Interval, converted to an hourly rate of electric energy delivery, in kWh per hour, that is equal to the product of Metered Energy for one Metering Interval, in kWh per Metering Interval, times the number of Metering Intervals in a one-

So for electric motor applications, output power is found by **multiplying the motor's rotational speed (angular velocity) by its torque output at that speed**. Note that angular velocity is expressed in radians per second (rad/s).

Firms can find out the marginal product by **deducting the previous quantity or level of output from the current production level**. Where, Q_{n} is the Total Production at time n. Q_{n}_{-}_{1} is the Total Production at time n-1.

How Do You Calculate Efficiency? Efficiency can be expressed as a ratio by using the following formula: **Output รท Input**. Output, or work output, is the total amount of useful work completed without accounting for any waste and spoilage. You can also express efficiency as a percentage by multiplying the ratio by 100.

If for some reason you need a larger transformer to operate appliances, you still **divide the wattage by the voltage** to find the current. For a 120-volt primary, 2000-watt transformer, divide 2000 by 120 for the current (2000 Watts /120 volts =16.67 amps). For a 240-volt, 3000-watt transformer, the current is 12.5 amps.

To calculate the power output, you should **multiply the Load/Amperage by the Line Voltage**.

Value of output refers to **the market value of goods and services produced by a firm in a given accounting period**.

N/A

- The output voltage can be calculated by the ohm's law.
- V = I * R.
- where, V = output voltage.
- I= Current passing through the circuit.
- R = Resistance offered in the circuit.

output. 1. The amount of coal or ore put out from one or more mines, or the quantity of material produced by, or turned out from, one or more furnaces or mills, in a given time. 2. (Science: physiology) **That which is thrown out as products of the metabolic activity of the body; the egesta other than the faeces**.

The formula for calculating wattage is: **W (joules per second) = V (joules per coulomb) x A (coulombs per second)** where W is watts, V is volts, and A is amperes of current. In practical terms, wattage is the power produced or used per second. For example, a 60-watt light bulb uses 60 joules per second.
