Years later, as an electrical engineer, Priya still kept a yellowed printout of problem 611 in her desk drawer—not as a shortcut, but as a reminder that the best resources aren’t always free. Sometimes, they’re a single, honest correction from a stranger who cared enough to post it.
Frustrated, she typed into a search engine: "electric circuit analysis book by bakshi free 611" electric circuit analysis book by bakshi free 611
She spent two hours working through it. Using the supernode method, she wrote KCL, solved the system, and got 1.73 mA. When she checked with a classmate who owned the book, the official answer was indeed 1.8 mA—but her simulation in LTSpice confirmed the forum’s correction. Her professor later admitted the typo and gave her extra credit. Years later, as an electrical engineer, Priya still
It was a sweltering evening in Mumbai, and 19-year-old Priya was staring at a mountain of unpaid lab fees. Her professor had just assigned the next chapter of Electric Circuit Analysis by Bakshi—specifically problem 611, a notorious nodal analysis challenge involving a supernode and a dependent source. Without the book, she was lost. The library copy was checked out. Buying it was impossible on her student budget. Using the supernode method, she wrote KCL, solved
“For Bakshi’s 611: The answer in the back is wrong. The correct current through the 2kΩ resistor is 1.73 mA, not 1.8. Redraw the circuit with the supernode equation first. Free advice from an old engineer.”
