A 24V transformer with a 40 VA rating can safely operate with a current of what value?

A 24V transformer with a 40 VA rating can safely operate with a current of what value?

• A. 1.33 Amps
• B. 1.67 Amps
• C. 2.00 Amps
• D. 2.50 Amps

Answer: (B)

To determine the safe operating current for a 24V transformer with a 40 VA rating, you can use the formula for power, which is expressed as: Power (VA) = Voltage (V) × Current (A) Rearranging this formula to solve for current gives: Current (A) = Power (VA) / Voltage (V) Substituting the values from the question: Current (A) = 40 VA / 24 V When you perform the calculation: Current (A) = 1.6667 A Rounding this value appropriately, we find that the transformer can safely operate with a current of approximately 1.67 Amps. This means that the correct answer aligns with the calculated value, confirming its accuracy based on the transformer’s specifications.

To determine the safe operating current for a 24V transformer with a 40 VA rating, you can use the formula for power, which is expressed as:

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

Rearranging this formula to solve for current gives:

Current (A) = Power (VA) / Voltage (V)

Substituting the values from the question:

Current (A) = 40 VA / 24 V

When you perform the calculation:

Current (A) = 1.6667 A

Rounding this value appropriately, we find that the transformer can safely operate with a current of approximately 1.67 Amps. This means that the correct answer aligns with the calculated value, confirming its accuracy based on the transformer’s specifications.
