To calculate electricity usage, multiply the power rating of the appliance in kilowatts by the time it was used in hours. Then, multiply this by the electricity rate in kilowatt-hours to determine the cost. Finally, multiply this by the number of days the appliance was used to get the total electricity usage.
A 700 watt small heater consumes 0.7 kWh of electricity in 1 hour. In 5 minutes, it would consume 0.0583 kWh (0.7 divided by 60, then multiplied by 5) of electricity.
A 60W light bulb consumes 1.44 kWh of electricity in a day (assuming it is on for 24 hours). The cost would depend on your electricity provider's rate per kWh, which varies but is typically around 14-20p per kWh in the UK.
Assuming an average electricity cost of $0.12 per kilowatt-hour, running a 60-watt light globe continuously for 5 days would cost about $7.20. This calculation is done by converting watts to kilowatts (60W = 0.06 kW), multiplying by hours in 5 days (120 hours), and then multiplying by the electricity cost.
1 kilowatt-hour is 1000 watt-hours and 60 watt bulb consume during 1 hour 60 watt-hours of electricity, so then it costs 0.6 cent =>60/1000=0,06*price of 1 kilowatt-hour = 0.6 cent
To calculate electricity usage, multiply the power rating of the appliance in kilowatts by the time it was used in hours. Then, multiply this by the electricity rate in kilowatt-hours to determine the cost. Finally, multiply this by the number of days the appliance was used to get the total electricity usage.
A 700 watt small heater consumes 0.7 kWh of electricity in 1 hour. In 5 minutes, it would consume 0.0583 kWh (0.7 divided by 60, then multiplied by 5) of electricity.
The amount of electricity a light bulb uses in a day depends on its wattage. For example, a 60-watt bulb used for 10 hours per day would consume 0.6 kilowatt-hours (kWh). You can calculate the electricity usage by multiplying the wattage of the bulb by the number of hours it's used, then dividing by 1000 to convert to kWh.
A 60W bulb will use 60W X 1 hour / 1000. this will give you the KWh - the units your electricity company uses to charge you.So 60 X 1 =6060/1000 =0.060 Kwh
A 60W light bulb consumes 1.44 kWh of electricity in a day (assuming it is on for 24 hours). The cost would depend on your electricity provider's rate per kWh, which varies but is typically around 14-20p per kWh in the UK.
Assuming an average electricity cost of $0.12 per kilowatt-hour, running a 60-watt light globe continuously for 5 days would cost about $7.20. This calculation is done by converting watts to kilowatts (60W = 0.06 kW), multiplying by hours in 5 days (120 hours), and then multiplying by the electricity cost.
1 kilowatt-hour is 1000 watt-hours and 60 watt bulb consume during 1 hour 60 watt-hours of electricity, so then it costs 0.6 cent =>60/1000=0,06*price of 1 kilowatt-hour = 0.6 cent
To find the total kilowatt-hours consumed, first calculate the total energy used by one bulb: 60 watts * 200 hours = 12,000 watt-hours or 12 kilowatt-hours. Then, multiply this by the number of bulbs (3) to get the total kilowatt-hours: 12 kWh * 3 = 36 kWh. The electrical energy consumed in the home is 36 kilowatt-hours.
A 60 watt bulb used for 1 hour consumes 0.06 kWh (60 watts * 1 hour / 1000).
To calculate the cost, first convert the hair dryer's power consumption to kilowatts: 1500 watts = 1.5 kW. Then, calculate the daily energy consumption: 1.5 kW * 0.5 hours = 0.75 kWh. Finally, determine the total cost: 0.75 kWh/day * 30 days * $0.12/kWh = $3.60.
To calculate the kWh used by a smoke detector, you need to convert the current from mA to A because kWh is a measure of power consumed over time. Given 120 VAC and 80mA, first convert mA to A (80mA = 0.08A), then calculate power (P = V x I) which is 120V x 0.08A = 9.6W. To find kWh, multiply power by the number of hours used. For example, if the smoke detector is used for 24 hours, kWh = 9.6W x 24 hours / 1000 = 0.23 kWh.
To calculate the cost of running a 60-watt bulb for an hour, you need to know your electricity rate per kilowatt-hour (kWh). If your rate is, for example, $0.12 per kWh, the cost would be 60 watts divided by 1000 to convert to kilowatts (0.06 kWh), multiplied by the rate ($0.12), equals $0.0072 per hour to run a 60-watt bulb.
