the professor thinks about the cruel irony of love ..
. attraction arising at the
end of a semester when the two souls will soon part ways. Not very
cool… omb, so he builds the resistor network shown at the upper
right (in picture) and hooks it to a 10 V DC source to see if the forces of love
can be resisted.
a) What is the equivalent resistance of this resistor network?
b) What is the voltage across the 5 2 resistor?
c) When the resistor network fails, he realizes that resistance
begins at ohm. So he constructs the R-L circuit shown at the lower
right. What is the current in the circuit 3.0 s after switch S is closed?
