Which statement accurately describes farther spacing of electrodes?

The accurate description of farther spacing of electrodes is that it targets deeper tissues. When electrodes are placed further apart, the electrical current has a greater distance to travel through the body. This increased distance allows the current to penetrate deeper into the tissues, effectively engaging muscles and nerves located at deeper levels.

In contrast, if electrodes are placed closer together, the current primarily affects the superficial layers of tissue. The design of electrode spacing directly influences the depth of tissue engagement, making it essential in therapeutic applications to consider how spacing affects treatment depth.

Regarding the other options, treating superficial tissues is associated with closer electrode spacing. A uniform current density is typically achieved with more strategic placement that balances current flow rather than simple distance. Lastly, the requirement for larger electrodes is not inherently connected to spacing; smaller or larger electrodes can be used depending on the treatment goals without necessarily affecting the depth of tissue targeted just based on size.
