A transformer has the voltages 25 V_pri and 140 V_sec. A current 3.5 mA is flowing in the primary. What is the current flowing in the secondary? (Assume 100 percent efficiency.) Submit Answer Save Progress Practice Another Version A machine in the factory needs 31V to operate. The power in the factory is different from that, so a transformer is needed. If the secondary to primary turns ratio {N_sec/N_pri) of the transformer is 0.0675, What is...
