A500-2 resistor, an uncharged 2.00-uf capacitor, and a 20.0-v emf are connected in series. you then close a switch to complete the circuit. (a) (6 points) what is the initial current just after you closed the switch? (b) (4 points) what is the rc time constant? (c) (12 points) what is the voltage on the capacitor after one-and-a-half (1.5) time constants? (d) (12 points) what is the current after one-and-a-half (1.5) time constants?
