Ideal transformer. An ideal transformer has a primary to secondary turn ratio of 10. If the transformers primary coil is connected to 110 V and transfers 150 W calculate:
(a) The voltage and current in the secondary.
(b) The current in the primary.
(c) The impedance of the primary and secondary coils. What is the ratio between the impedance in the primary and secondary?
what was the mass of the ore sample? Which of the four transition metal ions in this titration has the highest oxidation state?
