In the intensity equation, power is measured in what units?

Explanation:
Power is the rate at which energy is transferred, and its SI unit is the watt, defined as one joule per second. In the intensity equation, intensity equals power divided by area, so the power unit used is watts (with area in square meters, giving intensity in watts per square meter). Joules measure energy, Newtons measure force, and Volts measure electric potential difference, so they aren’t units of power.
