How many electrodes does a taser have that need to connect during testing?

A Taser, specifically the standard models used by law enforcement, typically has two electrodes that are designed to connect with the target during operation. These electrodes create an electrical circuit that delivers a high-voltage shock meant to incapacitate the individual temporarily.

While there may be multiple parts to the Taser system, including additional electrodes for testing and safety mechanisms, the functional aspect during actual use revolves around having two electrodes that connect with the target. Therefore, while it may seem that four electrodes are needed (two for connecting with the target and additional ones for other functions), only two are essential for testing the primary incapacitating function of the Taser.

The inclusion of other numbers, like three or five, does not adhere to the essential operational requirements of the device. Thus, the need to connect two electrodes is the standard for testing the effectiveness of a Taser.
