The electronics aboard a certain sailboat consume 50 w when operated from a 12.6-v source. if a certain fully charged deep-cycle lead acid storage battery is rated for 12.6 v and 100 ampere hours, for how many hours can the electronics be operated from the battery without recharging?

The power (in watt) is defined as the multiplication of the voltage and the current

[tex]P=I*V[/tex]

Then, the current equals [tex]P/V=\frac{50}{12.6}=3.9683 Amp\\[/tex]

Because the certain fully charged deep-cycle lead acid storage battery is rated for 12.6 v and 100 ampere hours (the same voltage)

so, the time which the electronics can be operated from the battery without recharging = [tex]\frac{100 Amp.hour}{3.9683Amp}=25.2 hours[/tex]
