To do this, we must find at least one loop current passing through every component in the circuit. nscn-w60 バッテリーを変えたら動かない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. nscn-w68 走行中テレビ

"WebTo use the component terminal notation we introduced in the Labeling Voltages, Currents, and Nodes section: V (V1.nA)−V (V1.nB)= 12 In this case, the terminal V1.nA is connected to node X, and the terminal V1.nB is connected to a ground node: V (X)−V (ground)= 12 By definition, V (ground)= 0 , so we have: V (X)= 12 " - Labeling every resistor with a current vector
