### Output Power Formula:

Output power signifies the usable or delivered power from a device or system. Measured in watts (W), it reflects the rate at which the device performs work, excluding any energy lost within the system itself.

Output power allows us to assess the effectiveness of a device. A higher output power for a given input power indicates better performance.

Output power is crucial for calculating efficiency. By comparing it to the input power (energy entering the system), we can determine how much energy is lost during conversion or transmission.

Every device or system starts with input power (Pi). This could be electrical energy from the wall outlet, chemical energy from fuel, or solar energy from sunlight.

The efficiency (E) of the device or system represents how well it minimizes these energy losses during conversion. A higher efficiency translates to less wasted energy and a higher output power for the same input power.

Finally, the output power (Po) represents the usable energy delivered by the device after accounting for these internal losses. It’s the rate at which the device performs its intended function.

Output power, Po(W) in watts is calculated by multiplying the input power, Pi(W) in watts with the efficiency, E in percentage.

Output power, Po(W) = Pi(W) * E /100

Po(W) = output power in watts, W.

Pi(W) = input power in watts, W.

E = efficiency.

### Output Power Calculation:

1. A solar panel has an input power rating of 200 watts (Pi) and a rated efficiency of 15%. What is the estimated output power (Po) of the solar panel?

Given: Pi(W) = 200 W, E = 15%

Output power, Po(W) = Pi(W) * E /100

Po(W) = 200 * 15 / 100

Po(W) = 30 W.

1. An electric motor delivers 80 watts (Po) of usable power and has an efficiency of 80%. What is the minimum input power (Pi) required for the motor?

Given: Po(W) = 80 W, E = 80%.

Output power, Po(W) = Pi(W) * E /100
