—Experiment of RLC series circuit with AC voltage is done in order to analyse the signal of the voltage through the AC source using oscilloscope, analyse the signal of RC, RL, and RLC series circuit and to measure the time constant through the RL series and RC series circuit. The principle of this experiment are signal generator as input device and oscilloscope as the output device. This experiment was done by reading the signal, Use three passive components, that are resistor 330 Ω, inductor 0.001 H, and capasitor 47 µF. This experiment use four frequency variations too, that are 10 Hz, 20 Hz, 30 Hz. And use three kinds of circuit, RL, RC, and RLC. From this experiment, we can know that the output signal of the AC generator is sinusoidal. Then the output signal of the RC circuit was like grass or can be called by sawtooth and the output signal of RL circuit was square. And for the output signal of RLC circuit was combination of both, like grass but there are vertical line. In this experiments, inductor leading and capacitor lagging. Phase for 10 Hz frequency is-45.76°, phase for 20 Hz frequency is-27.16° and phase for 30 Hz frequency is-18.87°.
