Which outcome occurs when a PLC controlling timed chemical injections in a batch reactor experiences a transient voltage spike?

💡 Explanation

Inaccurate reagent dosing occurs because electromagnetic interference causes bit errors in the PLC’s memory, leading to incorrect timer values via register corruption rather than other mechanical failures. Therefore, wrong amounts are dosed rather than a motor slowdown under excessive load.
