To find the electric field (V/m) given capacitance in picofarads (pF), the relevant equation involves the potential difference across a capacitor, which is calculated as QC, where Q is the charge and C is the capacitance. The electric field strength between the plates is determined by the formula QC/d, with d representing the distance between the plates. It is important to note that capacitance and electric field are distinct concepts, making the term "conversion factor" inappropriate in this context. Understanding the relationship between these variables is crucial for accurate calculations. The discussion emphasizes the need for clarity in terminology when addressing electrical concepts.
