How many farads are in 200 micro farads?

To convert microfarads to farads, it is essential to understand the metric prefixes used in the International System of Units (SI). The prefix "micro-" denotes a factor of (10^{-6}). Therefore, to convert 200 microfarads to farads, you can multiply by this factor:

200 microfarads = 200 × (10^{-6}) farads = 2 × (10^{2}) × (10^{-6}) farads = 2 × (10^{-4}) farads.

Thus, the correct conversion leads to the conclusion that 200 microfarads equals (2 × 10^{-4}) farads, confirming that this is indeed the correct answer. This highlights the importance of knowing the equivalent metric prefixes and performing proper conversions when dealing with different units of capacitance.
