A positive connection is one in which a change (increase or decrease) in some variable results in the same type of change (increase or decrease)in a second variable. The positive connection in the figure below for a cooling coffee cup implies that the hotter the coffee is the faster it cools.
The power consumption of small devices is usually measured in Watts, and the power consumption of larger devices is measured in kilowatts (kW), or 1,000 Watts. Electricity generation capacity is often measured in multiples of kilowatts, such as megawatts (MW) and gigawatts (GW).
Best Answer: Electricity is measured in volts, amps and watts. Volts measure the âpressureâ under which electricity flows. Amps measure the amount of electric current. Watts, named to honor the inventor of the steam engine, James Watt, measure the amount of work done by a certain amount of current under a certain pressure. One watt is a very small amount of power. On average, a typical household incandescent light bulb uses 40 to 100 watts.
