tice, alter-nating-current apparatusare always designed so asto have as large a powerfactor as possible consist-ent with economy. Itis possible to cut downthe effect of self-induc-tion by inserting a con-denser in the circuit, thuscutting down the lag ofthe current and increasing the power factor.… … Current Fie-. 404. 4G4 PRACTICAL ELECTRICITY. QUESTIONS 1. flow does an alternating current differ from a continuous ordirect current ? 2. What advantage has the alternating current over the directcurrent ? 3. What do you understand by the term frequency ? 4. How would you determine the frequency…
