Detailed Solution
Download Solution PDFThe correct answer is 4A
Concept
According to KCL, the algebraic sum of incoming and outgoing currents at a node are equal.
At node O:
\(I_1+I_2=I_3+I_4+I_5\)
Calculation
Assuming the voltage (V) at node A:
\({V-12\over 4}+{V\over 1}-2=0\)
\({V-12+4V-8\over 4}=0\)
V = 4 volts
The current across the 1Ω resistor is:
\(I_1={4\over 1}\)
I1 = 4 A
