Q4.Calculate the current I by successive source transformation. ТА br 5r site 2A or 1.52 34V

Answer 1

Hi friend...I hope this helps you....for any doubt feel free to comment.... thankyou

using Source Transformation & 650 2A ② V2 = 12 V Va = 2x6 =12 V TA 52 Vy m5r + Vy = 5x1= 5 V 3 172 1172 6345 Iz * Iz = 34 17 RA Now Equivalent circuit 1 W- 62 Vy + 62 5V $1.52 § 172 2A Va I2 6 12v again do Source Tronsformation 24 © fi Rx 5 Rz = 17 ||1.5 = 17X105_2 1:37842 17+1.5 Rz=1.37842

R2 = 137844 lg 2A 2hz V2 G 2.752V & Ra. 1.37842 1/2 = 1₂ R₂ = 2.75 68 V Equivalent circuit 512 62 w I by 6r & Vy 31:37842 Ta 12V ② 2 2.75 68 V Apply kv2 in 200p Il6+675 +1.3784) = 12+5 +2.7568 1 = 19.7568 18.3784 - 1•075 A I=1.07.5 A
