Q.

Refer to the figure given below. The values of I1, I2 and I3 are ________.                 [2026]

1 I1=2.5 A, I2=1.875 A, I3=1.875 A  
2 I1=1.875 A, I2=2.5 A, I3=1.875 A  
3 I1=1.875 A, I2=1.875 A, I3=2.5 A  
4 I1=2.5 A, I2=2.5 A, I3=1.875 A  

Ans.

(1)

Applying KCL at A

5-V12+0-V12+V2-10-V11=0    ...(i)

Applying KCL at B

5-V24+0-V24+V1-(V2-10)1=0    ...(ii)

On solving equation (i) and (ii), V1=0 and V2=7.5 volt

From the values of V1 and V2 we can find,

I1=2.5 A,  I2=1.875 A,  I3=1.875 A
