Watt Calculator

Step 1:

Enter the values of voltage and current below which you want to find the electrical power.

The Watt calculator finds the electrical power of a circuit using the given values.

Electrical power is given by

$P = V \cdot I$ $P = V \cdot I$
$P = Electrical power$ $P = Electrical power$
$V = Voltage$ $V = Voltage$
$I = Current$ $I = Current$

Step 2:

Click the blue arrow to submit. Choose "Find the Power" from the topic selector and click to see the result in our Physics Calculator!

Examples:

Find the Power

Fill in the given values you have, and we'll solve for the missing variable.

P = V I

$P = V I$

$P$ $P$	$=$ $=$	$power$ $power$
$V$ $V$	$=$ $=$	$12 V$ $12 V$
$I$ $I$	$=$ $=$	$45 A$ $45 A$
