    How do I find out the capacitor?

    V on capacitor = 12V - 2V = 10V now,charging formula for a capacitor is: Vs=Vi(1-[e to the power of t/RC]) where Vs is the supply voltage Vi is the voltage on capacitor t is the time R is the resistor and C is the capacitance therefor your formula will becoma 12=10(1- [e to the power...
