14 steashHW342d
Ex. 141. In exercise 140 what are the magnitudes of I4 (amps) and V4 (volts)?
I4 is the actual current through R4 and V4 is the actual voltage across R4.
What is the direction of 14? If toward the right, enter 1, or -1 otherwise.
What is the polarity of V4? If positive on the left, enter 1, or -1 otherwise.
ans:4
