Hello to all, this may seem a very simple question but i can't work it out and have no clue where to start.
My question is: A 6v battery charges up a 470 microfarad capacitor in 1 second, what is the final charge of the capacitor? and what is the current while the capacitor is charging?
i know capacitance is charge/potential or c = Q/V
i know charge is Q = CV
Is the final charge in coulombs, 470 microfarad x voltage? or should i convert microfarad to farad?
current i know means charge flowing per second but i do not know how to apply this to the question.
The final part of the question asks for the value of the resistor, is this just ohms law? R = V/I?
Any help would be much appreciated.
