What are the precautions to be taken to protect the circuits from electricity fluctuations?
Precautions to protect circuits from electricity fluctuations include several important measures.
Voltage regulators should be used to maintain stable voltage supply.
Adapters that convert high-voltage AC to low-voltage DC ensure steady power supply and prevent damage to sensitive components.
Avoid connecting electronic circuits directly to AC mains, as most home appliances use 230V AC supply while electronic circuits work on DC supply.
Batteries or DC power sources should be used when starting as a beginner.
Check for loose connections and short circuits before powering on.
Fuses or circuit breakers should be used to protect against overcurrent.
Ensure proper earthing to provide a safe path for excess current.
Explanation
The chapter warns that most home appliances use '230V AC supply' while electronic circuits work on 'DC supply'. It is dangerous to connect electronic circuits directly to AC mains. Beginners should only make circuits using DC batteries. The chapter also mentions using adapters that convert high-voltage AC to low-voltage DC to ensure steady power supply and prevent damage to sensitive components.
Solution Steps
Use voltage regulators to maintain stable voltage supply
Use adapters that convert high-voltage AC to low-voltage DC
Avoid connecting electronic circuits directly to AC mains
Use batteries or DC power sources when starting as a beginner
Check for loose connections and short circuits before powering on
Use fuses or circuit breakers to protect against overcurrent
Ensure proper earthing to provide a safe path for excess current
