To calculate the maximum amperage of a transformer, you can use the formula:

Maximum Amperage (A) = Volt-Amperes (VA) / Voltage (V)

For the given transformer with a rating of 20VA and primary voltage of 120V:

Maximum Amperage (A) = 20 VA / 120 V ≈ 0.1667 A

So, the maximum amperage of the 120V/24V, 20VA transformer is approximately 0.1667 Amperes or 166.7 milliamperes (mA).
