(^4) Lab 4 : Measurement of Capacitive Reactance and Impedance of a Series RC Circuit 4.4 Equipment:
- Function generator
- Oscilloscope
- Digital Multi Meter (DMM)
- 1 .5kฮฉ
- 0.1 ฮผF capacitor 4.5 Procedure:
- Using the DMM, measure the actual resistance of the resistor and note it down some where.
- Calculate the theoretical values of XC record in column XC(Theory) in Table 4 .1.
- Wire the circuit as shown in Figure 4.1. Figure 4. 1 : Schematic diagram of RC circuit.
- Set the function generator to generate a sinusoidal signal of 500 Hz and 1 volt peak (2 volts peak- peak).
- Measure the voltage across the circuit by using oscilloscope between points 1 and 3 and record in column Vt.
- Measure the voltage across the resistor between points 1 and 2 and capacitor between points 2 and 3 and record in columns VR and VC in the table.
- Calculate the total current in the circuit by using ๐๐ = ๐๐ ๐ and record in column It.
- Calculate the total impedance of the circuit by using ๐๐ = ๐๐ ๐๐ and record in column Zt.
- Calculate XC by using ๐๐คฐ = ๐๐^2 โ ๐^2 and record in column XC.
- Calculate the % deviation.
