In what units is energy density measured?
1. Watts
2. Watts per cubic meter
3. Newtons per meter
4. Joules per cubic meter
Homework Equations
E = cB (as derived by Maxwell)
The Attempt at a Solution
This question is so basic yet I'm confused. I thought "B" (magnetic field) had units of Tesla. I thought "c" (speed of light) had units of m/s. I was thinking the answer was Tm / s. I'm particularly confused as to where "per cubic meter" comes into play.
