the current in a circuit increases from 9.00 to 9.5 amps when the voltage is increased from 13.0 volts to a higher value. what is the percentage increase in the current?

To calculate the percentage increase in the current, you can use the formula:

\[
\text{Percentage Increase} = \left(\frac{\text{New Value} - \text{Old Value}}{\text{Old Value}}\right) \times 100
\]

In this case:
- **Old Value (Initial Current, \(I_{\text{initial}}\))** = 9.00 amps
- **New Value (Final Current, \(I_{\text{final}}\))** = 9.5 amps

Substituting the values:

\[
\text{Percentage Increase} = \left(\frac{9.5 - 9.0}{9.0}\right) \times 100 = \left(\frac{0.5}{9.0}\right) \times 100 \approx 5.56\%
\]

So, the percentage increase in the current is approximately **5.56%**.
