The capacitor and resistor are connected in parallel so I think that the resistor will draw a current I=VR but the capacitor is an ideal one therefore has no resistance and therefore draws an infinite amount of current which eventually stops when the capacitor is completely charged so overall. There is a subtle problem here with the logic The total resistance of resistors connected in parallel is the reciprocal of the sum of the reciprocals of the individual resistors. For example, a 10 ohm resistor connected in parallel with a 5 ohm resistor and a 15 ohm resistor produces 1 1/10 + 1/5 + 1/15 ohms of resistance, or 30 11 = 2.727 ohms The second principle for a parallel circuit is that all the currents through each resistor must add up to the total current in the circuit: \[I = I_{1} + I_{2} + I_{3}.\] Using these principles and our knowledge of how to calculate the equivalent resistance of parallel resistors, we can now approach some circuit problems involving parallel.
