E10P2 Problem 2: On a cold day a battery has a terminal voltage of V = 12.21 V and an internal resistance of r = 0.0065 Q. On a warm daythe battery has a terminal voltage of V = 11.67 V and an internal resistance of r2 = 0.022 2. The device it powers draws the same current at bothtemperatures. Assume the emf of the battery does not depend on temperature.Part (a) Enter an expression for the current, I, in terms of the given quantities.I=Part (b) Calculate the current, I, in amperes.Part (c) What is the battery's emf, in volts?

Here We have to use some basic formula

Problem 2: On a cold day a battery has a terminal voltage of V = 12.21 V and an internal resistance of r1 = 0.0065 2. On a warm day battery has a terminal voltage of V2 = 11.67 V and an internal resistance of r2 = 0.022 2. The device it powers draws the same current at both peratures. Assume the emf of the battery does not depend on temperature. Part (a) Enter an expression for the current, I, in terms of the given quantities.
