Homework Statement
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?
Homework 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
