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).
Kilowatt hour (kWh) is a unit of electrical power. 1 kWh corresponds to the consumption of a 1,000 watt electrical appliance for one hour.To calculate the consumption of an electrical appliance, you therefore have to multiply the capacity by the length of use expressed in hours and divide by 1,000 to obtain the number of kWh.Yes. kWh corresponds to the consumption of a 1,000 watt electrical appliance for one hour. To calculate the consumption of an electrical appliance, you therefore have to multiply the capacity by the length of use expressed in hours and divide by 1,000 to obtain the number of kWh. Yes.
