1. What is Output Power?

Output Power is the power supplied by the electrical machine to the load connected across it. It represents the useful power delivered to the system after accounting for all losses.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{out} \) — Output Power (Watt)
• \( P_i \) — Total Input Power (Watt)
• \( P_{loss} \) — Power Loss (Watt)

Explanation: The formula calculates the net power output by subtracting the power losses from the total input power.

3. Importance of Output Power Calculation

Details: Calculating output power is essential for determining the efficiency of electrical systems, evaluating performance, and ensuring proper power delivery to connected loads.

4. Using the Calculator

Tips: Enter total input power and power loss in watts. Both values must be non-negative numbers. The calculator will compute the output power.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between input power and output power?
A: Output power is always less than or equal to input power due to inevitable power losses in the system.

Q2: How is efficiency related to output power?
A: Efficiency is calculated as (Output Power / Input Power) × 100%, representing how effectively the system converts input power to useful output power.

Q3: What are common types of power losses?
A: Common power losses include resistive losses (I²R losses), core losses, friction losses, and heat dissipation.

Q4: Can output power be greater than input power?
A: No, output power cannot exceed input power as this would violate the law of conservation of energy.

Q5: How can I improve output power in a system?
A: Output power can be improved by reducing power losses through better design, higher quality components, improved cooling, and optimized operation.
