... I = dQ(t)/dt defines the current through a point. V = V(t) denotes the voltage across the point. Analysis Convention: When discussing current, we first assign a reference direction for the current I of each device. Then we have: I > 0 implies Q flows in the reference direction. I < 0 implies ...

... In each of these circuits, a current of 10/5 = 2 A will flow in the 5-ohm resistor. In the first one the resistor current will flow upwards and in the second one downwards, but the same power will be dissipated in the resistor in each case - 10 2 = 20 w. (We would have got the same answer by V 2/R ...
