Question

A circuit is constructed with five resistors and a battery as shown. The values for the resistors are: R1 = R5 = 43 A, R2 = 121 , R3 = 64, and R4 = 1300. The battery voltage is V = 12 V. R1 b 4 Ra R5 1) What is Rab, the equivalent resistance between points a and b? 76.92 Submit 2) What is Rac, the equivalent resistance between points a and c? 119.9 Submit 3) What is 15, the current that flows through resistor R5? A Submit 4) What is 12, the current that flows through resistor R2? A Submit 5) What is 11, the current that flows through the resistor R1? A Submit

Answer 1

Solution : Rol с. b R = Rs = 43 ; R2 = 121 R3=64 ; Rh=110 R2 Ru n zR3 V= 12 a RE (@) Rab = ? R, and Rs are in Series * RitRs = :86 R2 and R3 are in Series R2 + R3 = 185 Resultant of both in parallel torties 271 86 +185 Rab 868185 271 Rab = 58.70 2 0) Rac=? R , R2 R3 in Series R= 228 and Rs in parallel with combination Rac- 226 + to Rac 271 228843 = 228 +43 271 Rac 36.77 2

Req R2 and R3 in series = R2 + R3=185 + R2 + R3 Run I tl 130 185 315 185+130 R = 1858130 315 IR' 71.34 2 - R, and Rs and R' are in series Reff = 1/3 + 434 76-34 Reff 162.34 2 į Total ole 12 162-34 i rotal = 0.07A (C) Is = 0.077 Rs = 0.07443 – 3.17 d) Iz = 0.07+ R2 = 0.074 12) a 18-47A Cel I=0.07+43 =]3.17 A
If you have any doubt then mention in the commant.
