Differences Between AC and DC
- AC (Alternating Current): Current changes direction periodically.
- DC (Direct Current): Current flows in a single direction.
- Applications: AC is commonly used for power distribution due to its efficiency in long-distance transmission, while DC is used in batteries and electronic devices.
Applications of AC Circuits
AC circuits are used in household electrical systems, power transmission, and various electronic devices. They are crucial for the functioning of transformers, motors, and generators.

Q: What is the difference between peak and RMS values?
A: The peak value is the maximum value of the AC waveform, while the RMS (Root Mean Square) value is the effective value that produces the same power dissipation as a corresponding DC value.
Q: How does resonance affect AC circuits?
A: At resonance, a series RLC circuit impedance is minimized, leading to maximum current. In a parallel RLC circuit, resonance maximizes the circuit’s admittance.
Q: What are the best strategies for mastering AC circuit concepts?
A: Regular practice, visualizing waveforms, understanding the phase relationships, and using simulation tools can help master AC circuit concepts.
