Question

What is the maximum safe secondary current for a 40 VA transformer that has a primary voltage of 240 V and a secondary voltage of 24 V?

Answer 1

The maximum safe secondary current for a 40 VA transformer with a 240 V primary and a 24 V secondary is 1.67 amperes.

Step-by-step explanation:

The maximum safe secondary current for a 40 VA transformer with a primary voltage of 240 V and a secondary voltage of 24 V can be calculated using the formula:

Power (VA) = Voltage (V) × Current (I)

To find the maximum secondary current, we rearrange the formula:

Maximum Secondary Current (I) = Power (VA) / Secondary Voltage (V)

This gives us:

I = 40 VA / 24 V = 1.67 A

Therefore, the maximum secondary current is 1.67 amperes.
