Question

How many watts is 120 volts?

Answer 1

To determine the number of watts from volts, you also need to know the current in amperes. The formula is Watts = Volts × Amperes. For example, if you have 120 volts and a current of 1 ampere, it would be 120 watts. Do you have a specific current in mind?

Answer 2

To determine how many watts correspond to 120 volts, you need to know the amount of current (in amperes) flowing through the circuit. The formula to calculate power (in watts) is:

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

Here’s a step-by-step explanation:

1. **Identify the Voltage**: In your case, it's 120 volts.

2. **Determine the Current**: The current in amperes needs to be known or provided.

3. **Apply the Formula**: Multiply the voltage (120 volts) by the current (in amperes) to get the power in watts.

For example:

- If the current is 5 amperes:
  \[ \text{Power} = 120 \text{ V} \times 5 \text{ A} = 600 \text{ W} \]

- If the current is 10 amperes:
  \[ \text{Power} = 120 \text{ V} \times 10 \text{ A} = 1200 \text{ W} \]

Without knowing the current, it's impossible to determine the exact number of watts. You need both voltage and current to calculate power.
