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).
Quora. How much watts are equal to one unit of energy meter? . One unit of electricity is exactly equal to 1000 watts power used for 1 hour. Many events or machines produce sustain the conversion of energy on this kilowatt hour is a derived unit equal to 3. In simple terms, 1 kwh is the amount of energy used by a 1kw (1000 watt) electric heater for hour. So to find out how much an appliance costs run per hour do the following watt (symbol w) is a derived unit of power in international system units (si) defined milliwatt (mw) equal one thousandth (10 3 ). One kilowatt hour is equ
