Homework Review

3. Electric power P= IV All three forms are included in the data booklet.
Recall the work done when moving a charge through a potential difference: W = QV
Power = W/t = QV/t
I = Q/t
P= IV All three forms are included in the data booklet.
P= IV Sub V= IR P = I2R Recall Unit: Watt, W = J/s
P=IV Sub I = V/R P= V2/R
