Explanation:
The transformation ratio of a transformer is given by the ratio of the number of turns in the secondary winding to the number of turns in the primary winding. So, for a 1:10 step up transformer, the secondary voltage will be 10 times the primary voltage. Similarly, for a 1:5 step up transformer, the secondary voltage will be 5 times the primary voltage.
When the secondary of a 1:10 step up transformer is connected to the primary of a 1:5 step up transformer, the total transformation ratio can be calculated as follows:
- The secondary voltage of the 1:10 transformer is connected to the primary of the 1:5 transformer, which will step up the voltage by a factor of 5. So, the total transformation ratio is:
1:10 x 1:5 = 1:50
- This means that the secondary voltage of the 1:10 transformer will be stepped up by a factor of 5 to give a total voltage increase of 50.
- For example, if the primary voltage of the 1:10 transformer is 120V, the secondary voltage will be 120 x 10 = 1200V. When this voltage is connected to the primary of the 1:5 transformer, the secondary voltage will be stepped up to 1200 x 5 = 6000V.
- Therefore, the correct answer is option C: 50.
In summary, connecting two transformers in series multiplies their transformation ratios, resulting in a higher overall voltage increase.
