Shunts, Jumpers are passive components commonly used in electronic circuits to measure current or to achieve jumper connections between circuits. Shunts, usually referred to as low-resistance resistors, produce a small voltage drop when a current is passed through, and the current can be calculated by measuring this voltage drop. Shunts are a key component of current detection and protection circuits. Jumpers are small connectors for short-circuiting two or more points on a printed circuit board (PCB) that can be manually configured to change circuit paths and are often used for circuit debugging and prototyping. The design principle of these components is based on Ohm's Law, using precise resistance values and good thermal stability to ensure measurement accuracy and circuit reliability.
