ows. The effective current in an alternating-current circuit is equalto the effective voltage applied to the circuit divided by the impedanceof the circuit. Current =Voltfge . Impedance It might be assumed that if we had a resistance of 3 ohmsand a reactance of 4 ohms the impedance would be the… … Ohmic Resistance Fig. 226.—Ohmic resistanceand inductive resistance actat right angles. the inductive resistance. These two re-sistances are acting at right angles (90°)to each other. This is shown graphicallyin figure 226, in which the ohmic resistanceis represented by the horizontal line ACand…
