Extracted text: b) Figure 4 shows the arrangement of 3 resistors, which are connected to 3 sources: 70 V, 60 V and 80 V. Rajah 4 menunjukkan susunan 3 resistor, yang disambungkan pada 3 sumber: 70 V, 60 V dan 80 V. Using Kirchhoff's rules, find the current in each resistor shown in Figure 4. i) 4.00 kN 70.0 V 00.0 V 80.0 V 2.00 k2 Figure 4/ Rajah 4 ii) Find the potential difference pass through R1 and R2.
