Q1
In a transformer, if the primary coil has 100 turns and the secondary coil has 200 turns, what is the relationship between the primary and secondary voltages?
V_primary = V_secondary
V_primary < V_secondary
V_primary > V_secondary
V_primary = 2 * V_secondary
In a transformer, the voltage ratio is directly proportional to the turns ratio. Therefore, if the secondary coil has more turns, the secondary voltage will be greater than the primary voltage.

Q
Q: In a transformer, if the primary coil has 100 turns and the secondary coil has 200 turns, what is the relationship between the primary and secondary voltages?
Solution: In a transformer, the voltage ratio is directly proportional to the turns ratio. Therefore, if the secondary coil has more turns, the secondary voltage will be greater than the primary voltage.
Steps: 8
Step 1: Understand that a transformer has two coils: the primary coil and the secondary coil.
Step 2: Identify the number of turns in each coil. The primary coil has 100 turns and the secondary coil has 200 turns.
Step 3: Recognize that the voltage in a transformer is related to the number of turns in each coil.
Step 4: Use the formula for voltage ratio: Voltage in primary (V1) / Voltage in secondary (V2) = Turns in primary (N1) / Turns in secondary (N2).
