whichcontains resistance only.We shall see that in alternating-current circuits we very oftenhave to consider other factors besides resistance, such as induc-tance and capacity, which may cause the current to lag be-hind the voltage (Fig. y~P\ ^voltage218) or even to leadthe voltage (Fig. 219).The… … 316 ELECTRICITY AND MAGNETISM 216. Ohms Law in noninductive a-c. circuits. Sometimesthere is doubt about how to use Ohms Law (section 30) in a-c.circuits; hence it will perhaps be well to recall again that thislaw states the relation of voltage, current, and resistance only,and always holds true as…
