Homework Statement
Basically, I need to know the power dissipation (W) for three resistors using aw 12V battery: 120, 80, and 50 ohms.

Homework Equations
I think the formula for voltage drop is Voltage Drop = Resistance * Current, and I thought the formula for power dissipation was V^2/R.
The Attempt at a Solution
It also asks for the current, which I think is 0.05A and voltage drop across all three resistors.
I think the answers for voltage drop are 6, 4, and 2.5 V, and the current was 0.05A.
I thought the power dissipation for the three resistors were 1.2, 1.8, and 2.9 W.
The website says I got "at least one wrong." Thanks, WeBWork.
