Three capacitors C₁, C₂ and C₃ whose values are 10μF, 5μF and 2μF respectively, have breakdown voltages of 10V, 5V and 2V respectively. For the interconnection shown, the maximum safe voltage in Volts that can be applied across the combination and the corresponding total charge in μC stored in the effective capacitance across the terminals are respectively

If the 12 Ω resistor draws a current of 1A as shown in the figure, the value of resistance R is
