**ECET 210 Week 1 iLab AC Fundamentals, Sinusoidal and Other Waveform Characteristics**

**Laboratory Title:** AC Fundamentals, Sinusoidal and Other Waveform Characteristics

**Objectives:**

Helps students to be familiarized to oscilloscope and function generator by:

·Using oscilloscope to analyze periodic waveforms.

·Setting oscilloscope and function generator at different frequency (f), Time period (T), Amplitude (V_{p}), Peak-to-Peak (V_{pp}), RMS value, and V_{RMS.}

**Results:**

·Students get experiences about how manipulate oscilloscope and function generator to analyze periodic waveforms.

·Students have gotten Knowledge and techniques and could set different inputs in function generator to get appropriate periodic waveforms on oscilloscope screen.

**Conclusions:**

In conclusion, most of students found that this first Lab is a really introduction to AC fundamentals and periodic waveform characteristics in general.

**ECET 210 Week 2 iLab**

*Objectives:*

- To analyze a series AC circuit is containing an inductor (L) and a resistor (R) using Ohm’s Law and Kirchhoff’s Voltage Law.
- To simulate the RL circuit and observe the voltage drops and currents at different frequencies.
- To build a RL circuit and measure voltage drops and current at different frequencies.
- To prove that the power delivered by the source is equal to the sum total of power dissipated by all of the resistors in the circuit.

Is the power supplied by the source the same as that dissipated in the resistor?

What do you call the power lost in the inductor? What are the units?

What is meant by Power Factor Correction?

Construct a **Phasor Diagram** to represent the source voltage, source current, voltage drops, V_{R,} and V_{L} across the resistor and the inductor.

Can the phase information be obtained from an oscilloscope?
