Question

How many watts are in 1 ampere?

Answer 1

The number of watts in 1 ampere depends on the voltage (V) applied across the circuit. The formula to calculate power (in watts) is:

\[
P = V \times I
\]

Where:

1. \(P\) is the power in watts
   

1. \(V\) is the voltage in volts
   

1. \(I\) is the current in amperes
   

So, if you know the voltage, you can calculate the power.

For example:

1. If the voltage is 120 volts, the power would be:
   

  \[
  P = 120V \times 1A = 120W
  \]

1. If the voltage is 230 volts, the power would be:
   

  \[
  P = 230V \times 1A = 230W
  \]

Without knowing the voltage, you can’t directly say how many watts are in 1 ampere.
