Demos: 6C-08 Capacitor Resistor Effects

This demonstration shows the effects of alternating current when a resistor is placed in series with a capacitor. A signal generator regulates a continuous sine wave pulse through a circuit of a resistor and capacitor in series. The current in this circuit will peak before the voltage. The difference between the peaks of the current and voltage is called phase difference. For a capacitor in an AC circuit, the current will always lead the voltage. When the oscilloscope is placed separately across the resistor and the capacitor you can visualize the current leading the voltage through the circuit.
