Example of Volts to Watts Calculations

Converting volts to watts is an essential task in many electrical applications. The conversion requires knowledge of the current in amperes. The formula to convert volts (V) to watts (W) is:

W = V×A

Where:

  • V is the voltage in volts
  • A is the current in amperes

Here is a table showing examples of volts to watts conversions with currents of 1, 2, and 4 amperes.

Convert 5 volts to watts

To convert 5 volts to watts, you need to know the current in amperes. The formula to convert volts (V) to watts (W) is:

W = V×A

Where:

  • V is the voltage in volts
  • A is the current in amperes

Assuming different current values, here are the calculations:

  1. For 1 ampere (A):

    W = 5×1 = 5 watts

  2. For 2 amperes (A):

    W = 5×2 = 10 watts

  3. For 4 amperes (A):

    W = 5×4 = 20 watts

W = 5×4 = 20 watts

So, for 5 volts:

  • At 1 ampere, it is 5 watts.
  • At 2 amperes, it is 10 watts.
  • At 4 amperes, it is 20 watts.

Convert 12 volts to watts

Assuming different current values, here are the calculations:

  1. For 1 ampere (A):

    W = 12 × 1 = 12 watts

  2. For 2 amperes (A):

    W = 12 × 2 = 24 watts

  3. For 4 amperes (A):

    W = 12 × 4 = 48 watts

So, for 12 volts:

  • At 1 ampere, it is 12 watts.
  • At 2 amperes, it is 24 watts.
  • At 4 amperes, it is 48 watts.

Convert 120 volts to watts

Assuming different current values, here are the calculations:

  1. For 1 ampere (A):

    W = 120×1 = 120 watts

  2. For 2 amperes (A):

    W = 120×2 = 240 watts

  3. For 4 amperes (A):

    W = 120×4 = 480 watts

So, for 120 volts:

  • At 1 ampere, it is 120 watts.
  • At 2 amperes, it is 240 watts.
  • At 4 amperes, it is 480 watts.

Convert 240 Volts to Watts

Here are the calculations:

  1. For 1 ampere (A):

    W = 240×1 = 240 watts

  2. For 2 amperes (A):

    W = 240×2 = 480 watts

  3. For 4 amperes (A):

    W = 240×4 = 960 watts

So, for 240 volts:

  • At 1 ampere, it is 240 watts.
  • At 2 amperes, it is 480 watts.
  • At 4 amperes, it is 960 watts.
