![]() ![]() ![]() ![]() (no capacitors or inductors), regardless of whether the driving voltage or. We measured the time varying voltage across the capacitor in a RLC loop when. Ohms Law states that the current through a conductor between two points is. This extra amount of current might have caused the increased "voltage" value displayed. The three components consist of an inductor coil, a capacitor and a decade. When an alternating voltage is applied across a capacitor, the current leads the voltage by a phase angle of 90 degrees. My guess is that when the capacitor was fully charged, no current would run through it, thus meaning all of the circuit's current would be redirected through the voltmeter and treating it as if it were in series. The torque of the coil is proportional to the amount of current flowing through said coil. Quiz questions will revolve around capacitors and current flow. At this stage, the only explanation I have for this phenomena is the idea of current overflow into the voltmeter.įrom my understanding, a voltmeter measures voltage through the current flowing into the voltmeter which interacts with a magnetic field, turning a coil and displaying a voltage value. The problem is, with some of the latest time values, the voltage read by the voltmeter exceeded 12 volts, the input voltage in the entire circuit. The diagram is attached at the bottom of this post. I recently conducted an experiment with some peers where we measured the voltage across a charging capacitor in an RC circuit over a period of time. Hi everyone, I'm new to this forum so I apologise in advance if I may have posted in the wrong forum or made a similar error. ![]()
