Find the value of v if v1=20V and value of current source is 6A.
Find the value of v if v1=20V and value of current source is 6A. Correct Answer 12V
The current through the 10 ohm resistor=v1/10=2A.Applying KCL at node 1: i5=i10+i2. i2=6-2=4A. Thus the drop in the 2 ohm resistor = 4×2 = 8V. v1=20V; hence v2=20-v across 2 ohm resistor=20-8=12V v2=v since they are connected in parallel. v=12V.
