1┬аkW power is equal to ________. (kW┬аstands┬аfor┬аkilowatt.)
1┬аJ/s
1000┬аJ/s
10┬аJ/s
100┬аJ/s
1000┬аJ/s
The kilowatt (kW) is a unit of power in the International System of Units (SI). By definition, 1 kilowatt is equal to 1,000 watts, and since 1 watt is defined as 1 joule per second (1┬аW=1┬аJ/s), it follows that 1 kilowatt is equal to 1,000┬аJ/s.
The kilowatt (kW) is a unit of power in the International System of Units (SI). By definition, 1 kilowatt is equal to 1,000 watts, and since 1 watt is defined as 1 joule per second (1┬аW=1┬аJ/s), it follows that 1 kilowatt is equal to 1,000┬аJ/s.
Think of wattage as the 'speed' of energy usage; just as a kilometer is 1,000 meters, a kilowatt is 1,000 'joules-per-second' of energy flow.
Kilo means 1000: 'K' in Kilo for 'K' in 'Kilo-bucks' (thousands).
P=tWтАЛ тАФ Power equals Work done divided by time taken
1┬аkW=103┬аW=1000┬аJ/s тАФ Conversion of kilowatt to joules per second
Power is defined as the rate at which work is done or energy is transferred, expressed as P=tWтАЛ. The SI unit for work or energy is the joule (J), and the unit for time is the second (s). Thus, the unit for power is 1┬аJ/s, known as the watt (W). The prefix 'kilo-' represents a factor of 103 (1,000).
The SI unit of power is the Watt (W).
The prefix 'kilo' denotes a factor of 1,000.
Power measures the rate of energy consumption or production.
Standardized unit for rating electrical appliances.
Rating electrical motors and home appliances.
Measuring the power output of power plants or solar panels.
1 Watt (W) = 1 Joule per second (J/s).
Option B is correct because 1,000┬аJ/s accurately reflects the conversion of 1┬аkW to 1,000┬аW.
B is correct тАФ 1 kilowatt is equal to 1,000 watts, which is equivalent to 1,000 joules per second (1,000┬аJ/s).
Always remember that power is a rate (energy/time), while energy (like kWh) is the product of power and time.
