Find io and vo in the circuit Find va and i in the circuit o

Find i_o and v_o in the circuit.

Find va and i in the circuit of Fig. 2.26 122 vo 15 A 22 Figure 2.26 For Practice Prob. 2.7. Answer: 20 10 A.

Solution

APPLY NODAL ANALYSIS AT NODE VO

15=(VO/2)+(IO/4)+(VO/12)

FROM THE CIRCUIT

IO/3=VO/2

IO=(3/2)*VO

15=(VO/2)+(3VO/8)+(VO/12)

VO=15.652 VOLTS

FROM THE CIRCUIT

IO/3=VO/2

IO=(3/2)*VO=(3/2)*15.652=23.478 AMPS.
