Frequently Asked Questions

1. How do Jumper Wire colours impact circuit functionality?

Jumper wire color minimally affects circuit functionality. Although black and red often denote negative and positive connections, colors like green, blue, orange, and white are commonly used without specific meanings. Color choice mainly serves organizational purposes and clarity, rather than influencing circuit operation.

2. What are the differences between Male-to-Male and Male-to-Female Jumper Wires?

Male-to-Male (M-M) jumpers have identical connectors at both ends, typically pins or headers. Male-to-Female (M-F) jumpers feature a pin or header at one end and a socket or female header at the other. M-F jumpers connect components with different headers or connectors, like bridging a breadboard's male headers with a circuit board's female headers. On the other hand, M-M jumpers are employed when both components share the same type of header, such as connecting two breadboards with male headers. In essence, the key distinction lies in the connectors at each end, facilitating specific connections based on component compatibility.

3. Can Jumper Wires handle high-voltage circuits?

Jumper wires can handle low to medium voltage circuits, typically up to 250V and 2A​. However, they are not recommended for high-voltage circuits due to the risk of damage or injury. For high-voltage circuits, it is recommended to use specialized high-voltage wires or cables, and to follow proper safety precautions.
