When an external resistor of resistance R1 = 16 Ω is connected to the terminals of a battery, a current of 6.0

A flows through the resistor. When an external resistor of resistance R2= 62.4 Ω  is connected instead, the current is 2.0 A. Calculate: (a)   the emf of the battery and (b)   the internal resistance of the battery.
