Determine the correctness or otherwise of the following Assertion $[a]$ and the Reason $[r]$. Assertion: Fast decoupled load flow method gives approximate load flow solution because it uses several assumptions. Reason: Accuracy depends on the power mismatch vector tolerance. Both $[a]$ and $[r]$ ... reason for $[a]$. Both $[a]$ and $[r]$ are false. $[a]$ is false and $[r]$ is true.
