Power can be calculated using the formula P = VI, where P is power, V is voltage, and I is current.

• Power (P) can be calculated by multiplying the voltage (V) and current (I) values.

• The formula for power is P = VI.

• Make sure to use the appropriate units for voltage and current in the calculation.

• For example, if the voltage is 120 volts and the current is 5 amps, the power would be 600 watts.
