PHYS345 Electricity and Electronics

Hint for E3.12

Nodal analysis works OK; consider the equivalent resistance of the two 10 ohm resistors.

For mesh analysis as we have been setting it up, you may wish to interchange the 20 ohm resistor and the 1 A current source in your drawing.

Source substitution works great! Replace the 1 A current source in parallel with the 20 ohm resistor with the equivalent Thevenin generator and the answers appear as if by magic...
