A basic lighting system works at 8v, but currently it has a 12v DC source which gives it more light output, these 12v come from a conventional power source. It is necessary to design a voltage backup system which powers the lighting system by means of a 9v battery when a power failure occurs.

Question
A basic lighting system works at 8v, but currently it has a 12v DC source which gives it more light output, these 12v come from a conventional power source. It is necessary to design a voltage backup system which powers the lighting system by means of a 9v battery when a power failure occurs.
Expert Solution
Basic lighting system
The circuit operates for the basic lighting system works at 8 V, the LM7809 voltage regulator IC scaledown the 12V input voltage to 9V regulated output voltage. Also, a 12 V lead-acid battery of any Amp Hour (AH) is utilized to power this circuit. The circuit will give output current up to 1 ampere.
This type of circuit used is for the lightning operations that took place here.
