So, I'm refreshing my understanding and working through a textbook of problems.
I'm not getting the same answer as the textbook. Here is the problem.
A 1-kΩ ¼ W resistor and a 1.5-kΩ 1/8 W resistor are in series. What is the maximum amount of voltage that can be applied to this circuit without exceeding the wattage rating of either resistor?
My calculations are:
V = sqrt(0.25 x 1000)
V1 = 15.811
V = sqrt(0.125 x 1500)
V2 = 13.693
Vmax = 15.811 + 13.693
Vmax = 29.504 is my answer
The textbook says Vmax = 22.82V ???
Where did I go wrong? Did I overlook something?
