text: if the switch is closed on series curcuit consisting of a battery, resistor and capacitor? is the current i=vr? yes, this circuit of voltage, resistor and capacitor in series is called vcr circuit. the ohm's law is always true: i=v/r.the greater the resistance, the less current will be. this simple circuit has resonance frequencies. but it is from my memory of eit( engineer in training) examinations.
