5 / 8 67% 4. (a) A resistor network is shown in Figure 4). By applying the Kirchhoff's (6 murks) current law, determine the value of the currents , Ig and Le 1 W 15 Is-SOA w 17-100A WW 13-30A w 16-20A Figure 40 (b) As shown in Figure 4(b) a series RLC eruit is connected to a 50 V 50 Hz AC supply. The circuit consists of a 20 resistor, a 25 mH inductor, and a 200 a capacitor. 6) Determine the total impedance (2) in rectangular form (3 marks) (i) Calculate the supply current (I) in polar form, and (2 marks) thii) Calculate the voltages across the resistor (V), inductor (V), and capacitor (marks) (Vain polar form (iv) Sketch a phasor diagram to show the supply current (I). supply voltage (V). 15 marks) and voltages across the resistor (Ve). Inductor ( Vand capacitor (Ve) 50 V, 50 Hz R M. Fich (c) A student is doing is test for the LRC circuit similar with connection shown (6 marks) in Figure 4b). He takes a resistor with a low resistance value. Then, he randomly pocks an inductor and capacitor. At last, he connects a 220 V to all of them in series. However, it is found that the protection fuse of the circuit is blown. Identify the possible problem with explanation
