The kind that are like comforters that can keep a room pitch black at noon.
Why would you want to bump a kumquat on speed. Doesn't ir already have enough problems.
First calculate the two resistances by: (note to change all dimensions to meters) Resistance of a wire in Ω R ρL/A ρ is resistivity of the material in Ω-m L is length in meters A is cross-sectional area in m? A πr?, r is radius of wire in m Then add the two R's together. Use ohms law (1), E IR 2) Use power law, P E?I then energy is power x time. .
