## Homework Statement

http://imageshack.us/a/img62/5467/homeworkprob14.jpg

A. Find the no-load voltage of V

_{0}

B. Find Vo when RL is 450 kΩ

C. How much power is dissipated in the 30 kΩ resistor if the load terminals are accidentally short circuited

D. What is the maximum power dissipated in the 50k resistor?

## Homework Equations

V = IR

Voltage Division:

(Voltage across series resistor) = [(resistance) / total series resistance)](total input V)

Current Division (for 2 parallel resistors):

(current across parallel resistor) = [(other resistor) / (sum of parallel resistors)](total incoming current)]

## The Attempt at a Solution

I forgot how to deal with load-resistors, and not sure how they apply to a circuit like this.

I don't need help with part B because, well, that's straight forward, and you find parallel resistance first between the load and other one by V

because: (1/450 + 1/50)^-1 = 45Ω

then using voltage division when you have only 30k and 45k in series:

V knot = [45Ω / (45 + 30)Ω] (120V) = 72VStill need help for other parts though
