## Solving a Simple Circuit of Three Elements

A simple circuit is solved and power absorbed or supplied by each element is determined. KCL as well as Ohm’s law are used in solving the circuit. positive sign convention is used in determining element powers. It is shown and discussed how a source, here current source, can be neither absorbing or supplying power. It is also mentioned that resistors are passive elements and always absorb power/energy.

## Find Voltage Using Voltage Division Rule

Determine voltage across and using voltage division rule. Assume that , , , and Solution: Please note that the voltage division rule cannot be directly applied. This is to say that:

## Problem 1-14: Current of A Voltage Source

Two simple circuits are used to demonstrate the characteristic of voltage and current sources. In both cases, the voltage sources are in series with current sources.

## Problem 1-2: Power and Conductance of Resistors

Finding power and conductance of resistors from the current and resistance
