What is the wattage of a load if it is supplied with 208 volts and draws 20 amps?

• A. 2080 Watts
• B. 4160 Watts
• C. 1040 Watts
• D. 2000 Watts

Answer: (B)

To determine the wattage of a load given the voltage and amperage, we use the formula: \[ \text{Power (Watts)} = \text{Voltage (Volts)} \times \text{Current (Amps)} \] In this scenario, the load is supplied with 208 volts and draws 20 amps. Plugging these values into the formula: \[ \text{Power} = 208 \text{ volts} \times 20 \text{ amps} \] \[ \text{Power} = 4160 \text{ watts} \] This calculation shows that the correct wattage for the load under these conditions is indeed 4160 watts. The formula effectively shows how electrical power can be calculated from the voltage and current. Using this understanding, one can deduce the electrical consumption, which is crucial in various applications such as determining the load on electrical systems, sizing breakers, and ensuring equipment operates within safe parameters.

To determine the wattage of a load given the voltage and amperage, we use the formula:

[ \text{Power (Watts)} = \text{Voltage (Volts)} \times \text{Current (Amps)} ]

In this scenario, the load is supplied with 208 volts and draws 20 amps. Plugging these values into the formula:

[ \text{Power} = 208 \text{ volts} \times 20 \text{ amps} ]

[ \text{Power} = 4160 \text{ watts} ]

This calculation shows that the correct wattage for the load under these conditions is indeed 4160 watts. The formula effectively shows how electrical power can be calculated from the voltage and current.

Using this understanding, one can deduce the electrical consumption, which is crucial in various applications such as determining the load on electrical systems, sizing breakers, and ensuring equipment operates within safe parameters.
