## Mesh Analysis – Supermesh

The mesh analysis used to solve the circuit which has a supermesh. After solving the circuit, power of sources determined.

## Solve By Source Definitions, KCL and KVL

A DC resistive circuit consisting of one voltage source and one current source and three resistors is solved using source definition, KCL and KVL.

## Find currents using KVL

A simple circuit with two voltage sources and two resistors solved using only KVL.

## Turning Sources Off

Turning off a source used in solving circuits with the superposition, means setting its value equal to zero. A voltage sources become a short circuit when turned off. To turn off a current source it should be replaced by an open circuit. Dependent sources cannot be turned off.

## Ideal Independent Sources

The ideal independent voltage and current sources are explained. Their symbols and voltage-current characteristics are presented. It is shown how their definitions can be used to solve problems. Some examples are also provided to clarify their characteristics.

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

Finding power and conductance of resistors from the current and resistance

## Problem 1-1: Power of Elements

Finding the power of elements and determining which one is supplying power and which one is absorbing it.
