How to Use

To utilize the watt time calculator, simply input the values for voltage (V) and current (I) into the designated fields. Then, click the “Calculate” button to obtain the power (P) in watts.


The formula used in this calculator is straightforward:



  • P is the power in watts (W)
  • V is the voltage in volts (V)
  • I is the current in amperes (A)

Example Solve

Suppose we have a circuit with a voltage of 12 volts (V) and a current of 5 amperes (A). Using the watt time calculator:


So, the power consumption of the circuit is 60 watts.


Q: Can this calculator be used for DC and AC circuits?
Yes, the watt time calculator works for both direct current (DC) and alternating current (AC) circuits.

Q: What units should I use for voltage and current?
Make sure to input voltage in volts (V) and current in amperes (A) for accurate results.

Q: Is there any limit to the size of values I can input?
A: No, the calculator can handle a wide range of values for voltage and current.

Q: Can I embed this calculator on my website?
