Question

problem 32?

1. a battery can provide an average of 1.5 a of current for 24 h. what is its ampere - hour rating?
2. what average current can be drawn from an 80 ah battery for 10 h?

Explanation:

Step1: Recall the ampere - hour formula

The ampere - hour (Ah) is defined as the product of current (I) and time (t), i.e., $Ah = I\times t$.

Step2: Solve for the first part

Given $I = 1.5\ A$ and $t=24\ h$. Using the formula $Ah = I\times t$, we have $Ah=1.5\times24 = 36\ Ah$.

Step3: Solve for the second part

Given $Ah = 80\ Ah$ and $t = 10\ h$. Rearranging the formula $Ah = I\times t$ to solve for $I$, we get $I=\frac{Ah}{t}$. Substituting the values, $I=\frac{80}{10}=8\ A$.

Answer:

1. The ampere - hour rating of the first battery is 36 Ah.
2. The average current that can be drawn from the 80 Ah battery for 10 h is 8 A.
