Transformers are generally rated by the number of volts they can handle. The most common ratings are 115 V 230 V and 460 V. Transformers can also be rated by the amount of power they can handle measured in watts.
What is the name for the process of converting alternating current (AC) to direct current (DC)?
Answer 1: rectification.
What are the two types of DC power?
Answer 2: primary DC power and secondary DC power.
What is the name for the device that is used to change the voltage in an electrical circuit?
Answer 3: a transformer.
What is the primary use for transformers?
Answer 4: to increase or decrease the voltage in an electrical circuit.
How do transformers work?
Answer 5: Transformers work by using electromagnetic induction to change the voltage in a circuit.
What is the name for the two types of transformer?
Answer 6: Step-up transformers and Step-down transformers
What is the difference between a step-up transformer and a step-down transformer?
Answer 7: A step-up transformer increases the voltage in a circuit while a step-down transformer decreases the voltage in a circuit.
How are step-up transformers different from step-down transformers?
Answer 8: Step-up transformers are wound with more turns of wire than step-down transformers.
What is the name for the core of a transformer?
Answer 9: The magnetic core.
What is the name for the wire that is wound around the magnetic core?
Answer 10: The primary winding.
What is the name for the wire that is connected to the load?
Answer 11: The secondary winding.
What are the two types of magnets?
Answer 12: Permanent magnets and electromagnets.
What is the difference between a permanent magnet and an electromagnet?
Answer 13: A permanent magnet is a magnet that is always magnetic while an electromagnet is a magnet that is only magnetic when an electric current is flowing through it.
How do electromagnets work?
Answer 14: Electromagnets work by using an electric current to create a magnetic field.
How aretransformers rated?
Answer 15: Transformers are rated by their volt-amperes (VA) rating.
