9.6: Electrical Energy and Power
The power supplied from the battery is equal to current times the voltage, (P = IV). Definition: Electric Power. The electric power gained or lost by any device has the form [P = IV.] The power dissipated by a resistor has the form [P = I^2 R = dfrac{V^2}{R}.] Different insights can be gained from the three different expressions for electric power. For example, (P = V^2/R)
