Accumulator 82755

The battery capacity is 50 Ah. With a current of 5A, we charge the accumulator to 100% capacity in 10 hours. To what percentage of capacity can we charge the accumulator with a current of 2A in 15 hours?

Correct answer:

p =  60 %

Step-by-step explanation:

$$\begin{gathered} Q=50\text{Ah} \\ I=2\text{A} \\ t=15\text{h} \\ {Q}_2=I\cdot t=2\cdot 15=30\text{Ah} \\ p=100\cdot \frac{Q_2}{Q}=100\cdot \frac{30}{50}=\frac{100\cdot 30}{50}=\frac{3000}{50}=60\% \end{gathered}$$
