Question

A 12 Volt lead-acid car battery, engineered for "up to 500 or more charge/discharge cycles," has a rating of 95.0 Ampere-hours. It sells for $ 126.00. If initially fully charged, what is the total electrical energy that the battery can deliver before it needs to be recharged?

Answer 1

Step-by-step explanation:

Electrical energy = potential x charge

potential = 12V ,

Charge = 95 amp-hours

= 95 x 60 x 60 coulomb

= 342000 coulomb

Electrical energy stored in battery = 342000 x 12

= 4104000 J

= 4.1 x 10⁶ J .
