19) A step-up transformer is connected to a generator that is delivering 125 V and 95 A. The ratio of the turns on the secondary to the turns on the primary is 1000 to 1.Yay.20) A 150W transformer has an input voltage of 9.0 V and an output current of 5.0 A.
- What voltage is across the secondary?
- What current flows in the secondary?
21) A transformer has input voltage and current of 12V and 3.0A respectively, and an output current of 0.75A. If there are 1200 turns on the secondary side of the transformer, how many turns are on the primary side?
- Is this a step-up or step-down transformer?
- What is the ratio of output voltage to input voltage?
22) Scott connects a transformer to a 24V source and measures 8.0V at the secondary. If the primary and secondary were reversed, what would the new output voltage be?
