Conduction and Current. Polarization vs. Conduction Batteries, Current, Resistance Ohm’s Law and Examples Resistivity and Examples Power and Examples. Electrical Properties of Materials. Materials can do 2 things:. Store charge Initial alignment of charge with applied voltage
OK, but do not touch the other wire!
(heat of vaporization of squirrel)
P=IV = I2R = V2/R
<< Half the voltage and power are wasted!
