What happens if need 270 mfd and use 189-227?

Answer 1

If you need a capacitor with a value of 270 microfarads (mfd) and instead use one rated between 189-227 mfd, the circuit may not function as intended. The reduced capacitance can lead to insufficient filtering, timing, or coupling, potentially resulting in lower performance or instability in applications like power supply, audio circuits, or timing circuits. It's crucial to use the correct capacitance to ensure optimal operation.
