Problem 2 The analysis of electrical networks composed of resistance and voltage supplies is governed by three basic principles 1. Ohm's Law. The drop in voltage across a resistor R in the direction of an assumed current is proportional to the current. In other words, V-IR 2. Kirchoff's Law. The sum of all currents entering and exiting a node must equal zero. 3. Kirchoffs Voltage Law. The sum of voltage drops around any closed loop must sum to zero. Consider...
