Is this capacitor/resistance data correct?

I think I messed up on the current which has affected the rest of the data.

    Do you have a circuit schematic, diagram, drawing?

    or give a description.

    I don't know what the circuit is.

    is this a charged cap connected to a resistor in parallel?

    time constant is 14700 Ω x 10 mF = 147 sec

    so it would be 63% of initial value after 147 sec.

    63% of 2.8 volts is 1.76

    you have 1.11 volts at 150 sec, not very close.

    but currents: I = V/R = 2.32/14700 = 0.158 mA

    so your current calculations are all wrong.

    But this is if I guessed right about the circuit.
