Copper loss refers to the loss of energy that occurs due to the resistance of the copper windings in electrical devices like transformers and motors.
Here's how it happens:
- \( I \) is the current (in amperes),
- \( R \) is the resistance of the copper windings (in ohms).
Since copper is a good conductor, this loss is generally smaller than losses caused by other factors, but it still leads to energy waste, especially in high-current applications. That's why it’s important to design systems that minimize copper loss for better efficiency.
Here's how it happens:
- When electric current flows through the copper windings, they encounter resistance, which causes some of the electrical energy to be converted into heat.
- This loss is proportional to the square of the current flowing through the windings, following the formula \( P = I^2 R \), where:
- \( I \) is the current (in amperes),
- \( R \) is the resistance of the copper windings (in ohms).
