Q92. Which is more deficult .AC&DC
AC and DC both have their own challenges, but AC is generally considered more difficult due to its changing voltage and frequency.
AC involves constantly changing voltage and frequency, which can be more challenging to work with compared to the steady flow of DC.
AC circuits require additional components like capacitors and inductors to manage voltage and current fluctuations.
DC circuits are simpler to understand and troubleshoot since the voltage remains constant over time.
