The last digit in oscillating-type electrodes can indicate which of the following values?

The last digit in oscillating-type electrodes can indicate which of the following values?

• A. 0 and 1
• B. 0 and 2
• C. 1 only
• D. 0 only

Answer: (A)

The trailing digit on oscillating-type electrode designations acts as a simple binary flag, signaling one of two possible variant versions of the electrode. It isn’t about size, strength, or coating type; it’s a two-state indicator used to distinguish between the two versions the manufacturer provides. Because it’s a two-state code, the last digit can be either 0 or 1. That’s why the values indicated by the last digit are 0 and 1. Other digits (like 2) aren’t used for this purpose in these electrodes, so they don’t apply.
