Question: What is the relationship between the number of turns in the primary and secondary coils of a transformer and the voltages across them? (2023)

Options:

  1. V_p/V_s = N_p/N_s
  2. V_p/V_s = N_s/N_p
  3. V_p = V_s
  4. V_p + V_s = 0

Correct Answer: V_p/V_s = N_p/N_s

Exam Year: 2023

Solution:

The relationship is given by V_p/V_s = N_p/N_s, where V is voltage and N is the number of turns.

Questions & Step-by-Step Solutions

What is the relationship between the number of turns in the primary and secondary coils of a transformer and the voltages across them? (2023)
  • Step 1: Understand that a transformer has two coils: the primary coil and the secondary coil.
  • Step 2: The primary coil is where the input voltage (V_p) is applied.
  • Step 3: The secondary coil produces the output voltage (V_s).
  • Step 4: The number of turns in the primary coil is represented as N_p.
  • Step 5: The number of turns in the secondary coil is represented as N_s.
  • Step 6: The relationship between the voltages and the number of turns is expressed with the formula: V_p/V_s = N_p/N_s.
  • Step 7: This means that if you know the number of turns in both coils, you can find the relationship between the input and output voltages.
