Bench Task 02 Construct the circuit shown in Fig. 4. Set the function generator to generate wi(t) = 3/2 cos(240x t). Use a ammeter to measure the current at source and load for a circuit without correction and circuits with the parallel capacitor. Use the oscilloscope with the first channel showing the source voltage and the second channel showing the voltage across resistor Rs. Find the phase of source current by measuring the phase difference between the voltage of two channels. Calculate average/reactive power and power factor and fill out the corresponding cells in Table 3. a
