between B and C: a resistance of 80 lI
between C and D: a resistance of 750
between D and A: a resistance of 100 lI
between B and D: a resistance of 200 lI
between A and C: a voltage source of 20 V having an internal resistance of
4 lI. The positive terminal of the voltage source is connected to the node
A.
Calculate the current through the 750 1~ resistor.
[Hint: convert the delta connection ABD into the equivalent star.]
