Question

The voltage V in volts produced by a battery is a linear function of the current i in amperes drawn from it. The opposite of the slope of the line represents the battery's effective resistance R in ohms. For a certain battery, V=12 when i=1 and V=8.4 when i=10. I got .4 ohms for the effective resistance of the battery, but I did not find the voltage that the battery would produce when the current s 25 amperes.

Answer 4

To find the battery's voltage at 25.0 amperes, we calculate its resistance using the slope of the function defined by two points. The effective resistance is 0.4 ohms, and by applying Ohm's law with this resistance and 25.0 amperes, the battery's output voltage is found to be 10.0 volts.
