Homework Help: Question involving the RC of a discharging capacitor:

  1. Dec 1, 2012 #1
    1. The problem statement, all variables and given/known data

    A 200mF capacitor is charged to 10V and then discharged through a 250kW resistor. Calculate the potential difference across the capacitor at intervals of 10s

    3. The attempt at a solution
    Firstly, I am completely unsure how to obtain a value for R or C from a 'kW' resistor? Is this a typing error from my tutors behalf?
    Also, if such error was apparent, there is virtually no exponential decay if the value was intended to be 250kOHMS. Please help! Thanks.

    Hello Dongorgon. Welcome to PF !

    Maybe it's a 250kΩ resistor and a 200μF capacitor.
