## Homework Statement

From the above circuit find V

_{CB}and V

_{DG}

Know Data:

V

_{E}= 0 (ground)

## Homework Equations

KCL and Ohm's Law are used in Node Voltage Method.

## The Attempt at a Solution

*I decided I would determine the node voltages then work out V*

_{CB}and V_{DG}afterwards.1. KCL and Ohm's law at Node C

## 15 + V_F + V_D = 3 V_C## -(1)

2. Super Node at EG

2.1 KCL and Ohm's law for all currents entering

## 2(V_F - V_G) = 2 V_E - V_D - V_B##

## 2(V_F - V_G) + V_D + V_B = 2 V_E## -(2)

2.2 Potentials at Nodes E and G## 2(V_F - V_G) + V_D + V_B = 2 V_E## -(2)

## V_G = -5V## -(3)

3. KCL and Ohm's law at Node D

## V_C = 2 V_D## -(4)

*This is as far as I got I am unsure what to do next so I can get 5 equations so they can all be solved simultaneously.*
