Approximately how many amps does the 300 W lamp draw when lit?

To determine how many amps a 300 W lamp draws when lit, you can use the formula that relates power (in watts), voltage (in volts), and current (in amps). The formula is:

Power (W) = Voltage (V) × Current (A)

To find the current in amps, rearrange the formula:

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

Assuming the lamp operates on a standard voltage, such as 120 V (which is common in residential applications in the U.S.), the calculation would be as follows:

Current (A) = 300 W / 120 V = 2.5 A

Hence, a 300 W lamp operating at 120 V indeed draws approximately 2.5 amps when lit. This matches the correct choice among the options provided. The other calculations would present values outside the expected current draw for a 300 W lamp at standard voltages, making them less applicable in this scenario.
