Q1. Which is more deficult .AC&DC
Ans. 
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 tro...read more

Q3. What is Ohm's law?
Ans. 
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
• Ohm's law is represented by the equation I = V/R, where I is the current, V is the voltage, and R is the resistance.

• It is named after Georg Simon Ohm, a German physicist who first formulated this law.

• This law is applicable to all types of circuits, including DC and AC circuits.

• It is use...read more
