Two resistors, R1 = 20-ohm and R2 = 30-ohm, are connected in parallel to each other, and this combination is connected across a 30-V source of emf. The current through the resistor R2 is:
I 204 D C I2 300 B I 30V R = 20 R23301 in parallel combination RELE RIRO Rit Ry 20x30 20+30 600 50 Roq = 120 Ror I= 30 12. I - 2.5 amp in Parallel combination botontial difference always same VAB = VCD R, I, = Rp 12 - 0 Ii +I2 = 12 I= 12-Iz R, (12 - 12) = R2 12 12R, - R, I2 - Ral 12R - I 2 Rit R2 12820 240 I2= 20+30 50 4.8 amb. I 2 = 4.8 amb Answer,
