What is the total electrical energy used by a 1500 watt hair dryer operating for 6.0 minutes?
Energy consumed = wattage x seconds used.
=1500 x 6 x60 J
=540 kJ
What is the total electrical energy used by a 1500 watt hair dryer operating for 6.0 minutes?
the 1500 watt should be out of an hour, and 6 minutes is 1/10 of an hour (or .1 or it) , so 1500 x .1 = 150 watts.
What is the total electrical energy used by a 1500 watt hair dryer operating for 6.0 minutes?
Its 150 Watt-hours I'd have to look up the conversion to joules.
What is the total electrical energy used by a 1500 watt hair dryer operating for 6.0 minutes?
A watt (power) is the amount of energy (1joule) per unit time (sec)--therefore 1Watt = 1 joule/sec. If the hair dryer is rated at 1500 Watts of power, then it will use
Power = Energy / time or Energy = Power * time
Energy = 1500 W * 6 minutes * 60 sec/minute
= 540,000 joules of energy.
What is the total electrical energy used by a 1500 watt hair dryer operating for 6.0 minutes?
1500 Watts x 0.10 Hour = 150 Watt Hr = 0.150KWH
1KWH = 3,600.000J
0.150KWH = 540,000J
Check my math
