None if your plugged in to the neighbors electricity!!
None if it's unplugged. It may be using a small amount if it is left plugged in. When the hair dryer is not being used it uses no electricity.
15 min = ¼ h Energy = (1.200 kW) * (¼ h) = 0.3 kWh
it takes up 3500 kWh
about 10,000 KWh
100 kWh
When you get your electric bill, look to see how many kilo watt hours (kWh) you used for the month. Then how much the bill cost. take the price divided by the (kWh). This is truly what your paying per (kWh). One (kWh) is 1000 watts being used for a hour, so one 100 watt light being used for 10 hours = 1 (kWh) or a 1500 watt hair dryer being used for an hour = 1.5 (kWh). so if your appliance power use is listed in amps, take amps x volts to figure out the watts. Plus determine how often the appliance runs. this will give You an idea of cost.
To find kWh a time frame has to be given. That is what the h in kWh stands for.
About 3 kWh's of heat are created for every kWh of electricity it consumes
In ten hours, a 200W bulb will use: 10 * 200 = 2000 Watt-hours = 2 kwh
Total Energy used=1.6x(20/60)x6*0.12=0.38p
Over 640,000 on the average
