A transformer rated 60 VA with a 12 V secondary provides how many amperes?

• A. 5 A
• B. 2 A
• C. 6 A
• D. 12 A

Answer: (A)

The current capability on the secondary is found by dividing the transformer’s VA rating by the secondary voltage. So 60 VA divided by 12 V equals 5 A. This means the transformer can deliver up to 5 amperes on the 12 V secondary under its rated conditions. Drawing more than 5 A would exceed the rating (for example, 6 A would be 72 VA), risking overheating and voltage drop.
