Q1. Explain working of ac-dc converter
Ans. 
AC-DC converter converts alternating current (AC) to direct current (DC) for various applications.
• AC voltage is converted to DC voltage using rectifiers

• Rectifiers can be half-wave, full-wave, or bridge rectifiers

• Filtering is done to smooth out the output voltage

• Examples include power supplies for electronic devices and battery chargers
