Question

In the following circuit, V = 55 volts, R₁ = 3 Ohms, R₂ = 5 Ohms, R₃ = 3 Ohms, R₄ = 10 Ohms, and R₅ = 6 Ohms. What is the current through R ₃ in amps?

Ri w 3 R2 + 4 mm R5

Answer 1

R,=32 ww 55 V - 1 R5 bri Apply KuL in loop 0 -vrir,+(91-92) R2 + 9, R5=0 (Rit R₂ +R5)9,- R₂ iz =v . (3+5+6)91-592=55 149,-512 = 55 (1) Apply kuL in loop ③ (22-P) R₂ + R392 + R4.??=0 -9, R2 + (R2+R3 +R4) 2=0 -59, +(5+3+10)12=0 -54, + 1812:= 0 - 2(2) on solving ..ean. (on and eqin (2) We get, 9i= goo Let a = 4.361 A 12= 275 A - 1.211 A from the above figure, current through Rp is ? * Current through Rg is 1.211 A (Answer) 227 Cor) / 2.75 227
