There is this really nifty facility called "Google Search". You would be well advised to learn how to use it.

After one time constant the capacitor will be charged to about 0.632 * 500V.
Now you just need to calculate the voltage that drops over the resistor and divide that by 200 Ohm.

do i have to say every time i post something that these questions are just out of book and i need quick answers my book doesn't contain a lot of info about the capacitor your posts arent helpful i am in vacation i just solve these questions to apply for a university test which will contain questions from many books not in my high school unfortunately and when i googled it i found really complex things

do you mean that the final voltage will be 500-316=184 and current will be 0.92 amp or i have to do something else thanks for your help dr i really appreciate it but my friend told me that the resulting voltage will be opposite in direction to that of battery can you explain how the capacitor work thx.
