Help needed on Intro to EE, Howework Problem

[memphisBred]

Design a series voltage divider to simultaneously provide 1, 5, 10, and 20 volts from a 25V source. The source will deliver 25 mW of power to the divider.

Might want to get Ray's attention.

Yeah there's a few people on here I'd like to get help from. Hopefully they'll see it.

All you need is the voltage?

Or do you need to know what wattage each comsumes?

All you need is the R values.

Easy but im on the road right now.

Does that mean you're SMD'ing and driving? Good thing they haven't passed a law restricting that...

[memphisBred]

That's the exact question given. I'm guessing the picture/sketch is as important as the math/work. Just the R value I believe.

[memphisBred]

Do you use P=IV to get the current then use ohms law to get the resistance?

Components are in series.

Therefore the current around the loop is the same through all components.

You know power from the source and it's voltage.

P/V=I

Don't suppose you've covered Kirchoff's Voltage Law yet...?
