The Answers to the top half are not I1 = 41/10 = 4.1 A I2 = 4 - 4 x 4.41 = -12.8

Question

The Answers to the top half are not

I1 = 41/10 = 4.1 A

I2 = 4 - 4 x 4.41 = -12.81 A

I3 = -12.81 + 4.1 = -8.71A

A previous chegg 2ter answered this and when I put it in it was incorrect

PRACTICE IT Use the worked example above to help you solve this problem. Find 11, 12, and 13 in figure a, where = 15 V 4.0 10V 6.0 2.0 EXERCISE HINTS: GETTING STARTED II'M STUCK! Find the three currents in figure b, where R = 2.7 . (Note that the direction of one current may have been chosen wrongly!) Need Help? 1-Read it

Explanation / Answer

By applying Kirchoff current law at right node,

i1+i2-i3=0

Applying kirchoff voltage law in top loop,

15 +4*i2 + 10 - 6*i1 = 0

Applying KVL in bottom loop,

10 - 6*i1 - 2*i3=0

Solving these three equations

i1 =2.0455 A

i2 = - 3.1818 A

i3 = - 1.1364 A
