Step down 2:1 Transformer Quiz
easy
5 Questions
Question 1 of 5
In a 2:1 step-down transformer, the primary voltage is 120V. What is the secondary voltage?
In a 2:1 step-down, the secondary voltage is half of the primary voltage.
Question 2 of 5
If the primary winding has 100 turns, how many turns does the secondary winding have in a 2:1 step-down transformer?
A 2:1 step-down means the secondary turns are half the primary turns.
Question 3 of 5
What is the relationship between primary and secondary currents in an ideal 2:1 step-down transformer?
Inversely proportional: Vp/Vs = Is/Ip.
Question 4 of 5
A 2:1 step-down transformer is designed to operate at 50Hz. What is the frequency of the output voltage?
Transformers do not change the frequency of the AC signal.
Question 5 of 5
If a 2:1 step-down transformer has a primary current of 2A, what is the approximate secondary current (assuming ideal transformer)?
Current steps up inversely proportional to the voltage step down. Is = 2 * Ip
