Question

14. A 12V car battery can provide 60.0 A for 1.0 h. how much energy is stored in the battery?

Answer 1

Explanation:

Your answer is here with explanation I hope it's right.

Answer 2

$\Huge{\underline{\underline{\mathfrak{Answer \colon}}}}$

From the Question,

• Potential Difference,V = 12 V

• Current,I = 60 A

• Time taken,t = 1 hr = 60s

Now,

$\huge{\boxed{ \boxed{\sf{W = Vq}}}}$

But,

$\sf{l = \frac{q}{t} } \\ \\ \rightarrow \: \large{ \underline{ \boxed{\sf{q = lt}}}}$

We get,

$\huge{ \boxed{ \boxed{ \sf{W = Vlt}}}}$

Substituting the values,we get :

$\sf{E = (12)(60)(60)} \\ \\ \implies \: \sf{E = 12 \times 3600} \\ \\ \huge{\implies \ \sf{E = 43200 \: J}}$

Thus,the energy stored by the battery is 43.2 KJ
