From a battery a current of 2.0 A, with a voltage of 114.2 V. When Amperage is increased to 8.0 A, the voltage drops to 112.6 V.
Find electromotive power, and the internal resistance of the battery.
How do i do this? Simultaneous equations with the formula r_i=(E-U)/I or by differentiation, or??
Thanks in advance.
