"WebIn calculating the power in the circuit of Figure 19.21, we used the resistance and Ohm’s law to find the current. Ohm’s law gives the current: I = V / R, which we can insert into the equation for electric power to obtain. P = I V = ( V R) V = V 2 R. This gives the power in terms of only the voltage and the resistance. " - Resistors units
