Industry:Energy
The rate of energy transfer equivalent to one ampere under an electrical pressure of one volt. One watt equals 1/746 horsepower, or one joule per second. It is the product of Voltage and Current (amperage).
Industry:Energy
The rate of heat flow required to maintain a specific indoor temperature; usually measured in Btu per hour.
Industry:Energy
