Final Answer

Attached.

The objectives of the experiment are to help us develop skills with the oscilloscope
as a voltage measuring instrument and learn how measure the impedance of an
element using a current sensing resistor. We can also compare and measure the
nameplate of a resistor capacitor and inductor.

EQUIPMENT REQUIRED
1. Resistors
1---100 Ω,1.2k Ω , 3.3 k Ω
2. Inductors
2---10 mH
3. Capacitors
1--- 0.47 uF, 1 uF
4. Instruments 1--- DMM,
1--- Oscilloscope,
1--- Audio oscillator,
1--- Frequency counter
