PHYS345 Electricity and Electronics

Hint for 3.5

Here again, there are three non-trivial nodes; at first glance there would seem to be a problem -- three nodal equations and four unknown quantities: V1, V2, V3, and the unknown current. However, please notice that V3 - V2 = 3 V, which quickly provides the needed fourth equation.

The nodal equation for the middle node may be written as:
(V2 - V1).2 + V2.4 + I = 0.
