Question

A heating element in a plate warmer in a restaurant is rated to deliver 4.5 kW at 240 volts. How many amps does the plate warmer draw at 240 volts?

Option 1: 18.75 A
Option 2: 12 A
Option 3: 6 A
Option 4: 9.375 A

Answer 1

The plate warmer rated at 4.5 kW at 240 volts draws 18.75 amps, making Option 1: 18.75 A the correct answer.

Step-by-step explanation:

The question asks about the amount of current a heating element rated at 4.5 kW at 240 volts draws. To find the current (I) drawn by the plate warmer, we use the formula I = P/V, where P is the power in watts and V is the voltage in volts. Substituting the values, we get I = 4500 W / 240 V = 18.75 A.

Therefore, the plate warmer draws 18.75 amps at 240 volts and the correct option is 1: 18.75 A.

To find the amount of amps drawn by the plate warmer at 240 volts, we can use the formula: power (in watts) = voltage (in volts) x current (in amps). We know that the plate warmer is rated to deliver 4.5 kW (4500 watts) at 240 volts, so we can rearrange the formula to solve for current: current = power / voltage. Plugging in the values, we get: current = 4500 watts / 240 volts = 18.75 amps. Therefore, the correct option is Option 1: 18.75 A.
