Which type of resistor is designed for large currents and is more accurate?

A wire wound resistor is specifically designed to handle large currents due to its construction, which involves winding a wire, typically made of a material with a high melting point and good conductivity, around a core. This arrangement allows it to dissipate heat effectively, making it suitable for high-power applications.

In addition to its capability to manage large currents, a wire wound resistor typically has a tighter tolerance than carbon resistors, which means it can provide more accurate resistance values. The manufacturing process for wire wound resistors allows for more precision in their dimensions, leading to more consistent electrical performance.

This combination of high current handling and accuracy is why wire wound resistors are preferred in many applications where performance is critical, such as in precision measurement instruments and industrial equipment.
