A PARALLEL RC CIRCUIT, WITH TIME CONSTANT OF 10 SECONDS, CONNECTED TO A 50V DC. after several minutes have elapse. a current of 50 micro amps is flowing. Find the value OF THE CAPACITOR and RESISTOR.

PLIS IF ANYONE JUST GIVE AN ANSWER TO THIS I WOULD BE VERY GREATFUL.
I NEED TO FIND THE CAPACITOR AND RESISITOR VALUE. I guess i need to find the several minutes that has elapse, which is the (t)
 

After several minutes the capacitor will be fully charged so the only current will be going through the resistor. 50V and 50uA sounds like a 1M ohms resistor - 50/50u.

So now you know R and the time constant is 10 seconds which is CR so you should be able to work out C as 10/R = 10uF.
