- A mobile x-ray imaging system operates on 110 V AC power. Its maximum capacity is 110 kVp and100 mA. What is the turns ratio of the high-voltage transformer?An ideal transformer has 600 turns on its primary side and 100 turns on its secondary side. The primary voltage is 1000 V AC a. What will the secondary voltage be with this configuration? b. What is the secondary current if the primary current is 100 A?A transformer is a device that takes an input voltage and produces an output voltage that can be either larger or smaller than the input voltage, depending on the transformer design. Although the voltage is changed by the transformer, energy is not, so the input power equals the output power. A particular transformer produces an output voltage that is 300 percent of the input voltage. What is the ratio of the output current to the input current?
