A 9.0V battery with internal resistance 0.20Ω is connected to a fixed resistor of 10Ω in series. To protect the resistor, the current must not exceed 0.60A.
(a) Calculate the resistance that should be added in series so that the current does not exceed the specified limit.
(b) After the additional resistor is connected, determine the power dissipated in (i) the 10Ω resistor and (ii) inside the battery.
