Comparison with Two Winding Transformers

What is the purpose of the turns ratio in a transformer?

• To determine the ratio of voltage between the primary and secondary coils.

• To measure the temperature of the transformer

• To calculate the resistance of the transformer

• To determine the weight of the transformer

How does the turns ratio affect the voltage in a transformer?

• It directly influences the ratio of input voltage to output voltage.

• It only affects the current in the transformer

• It causes the voltage to decrease

• It has no effect on the voltage

Can the turns ratio of a transformer be less than 1? Why or why not?

• Yes, because the turns ratio can be negative

• Yes, because the turns ratio can be a fraction

• Yes, because the turns ratio is not limited to whole numbers

• No

What is the function of the primary winding in a transformer?

• Step-up or step-down the voltage

• Generate electricity

• Regulate the current

• Store energy

What is the role of the secondary winding in a transformer?

• To generate electricity

• To store energy

• To reduce the voltage from the primary winding

• To convert the induced voltage from the primary winding into a different voltage level

Explain the difference between primary and secondary windings in a transformer.

• The primary winding is connected to the input voltage source, while the secondary winding is connected to the load.

• The primary winding is used for stepping up the voltage, while the secondary winding is used for stepping down the voltage.

• The primary winding has fewer coils than the secondary winding.

• The primary winding is connected to the load, while the secondary winding is connected to the input voltage source.

How does the voltage in the primary winding compare to the voltage in the secondary winding of a transformer?

• Lower

• Equal

• Higher

• Unrelated

What happens to the current in the secondary winding if the current in the primary winding of a transformer increases?

• The current in the secondary winding remains the same.

• The current in the secondary winding increases.

• The current in the secondary winding decreases.

• The current in the secondary winding becomes zero.

What is the significance of magnetic flux in a transformer?

• Has no effect on the operation of the transformer

• Allows for the transfer of energy between the primary and secondary coils

• Reduces the efficiency of the transformer

• Causes the transformer to overheat

How does the magnetic flux change when the number of turns in the primary winding of a transformer is increased?

• Magnetic flux remains the same

• Magnetic flux decreases

• Magnetic flux increases

• Magnetic flux becomes zero
