(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 2.7 kOhms and a 3.8 kOhms resistor are connected in parallel; this combination is connected in series with a 1.5 kOhms resistor.

If each resistor is rated at 0.9 W (maximum without overheating), what is the maximum voltage that can be applied across the whole network?

2. Relevant equations

parallel resistors 1/Req = 1/R1 + 1/R2 + 1/R3 ...

resistors in a series Req = R1 + R2 + R3 +...

Vab = E- IR

I= V/Req

3. The attempt at a solution

i have no idea. please help!
