An electric iron is marked 20 volts 500W The units consumed by it in using it for 24 hours?
Sandalian
The voltage is probably either around 110 or around 220, since those are the standards for common household current. However, this is not relevant for calculating the answer.
Standard SI units: 500 Watts means that 500 Joules are used every second. (A day has 86400 seconds.)
However, you may prefer to do the calculation in kWh in the first place, since that is the unit used by electricity companies to charge for the energy used. Since 500 W is 0.5 kW, this means that every hour, 0.5 kWh is being used.

Electric energy usage on your electric bill is measured how?
Electric energy is measure in Units which are kilowatt-hours. Your electricity meter records the usage in Units over the billing period. The meter measures the true power and not the volts times the amps.
Out of 100 units of electric energy 20 of those units are used to produce light and 30 of those units are used to produce sound if the rest is converted into heat how many units of electric energy?
50 units
How do you convert giga watts electric to kilo watt hours?
Gigawatts and kilowatts are units of power, and 1 gigawatt = 1 million kilowatts. Energy is measured in kilowatt-hours or gigawatt-hours, 1 gigawatt-hour = 1 million kilowatt-hours.
How much electricity in Indian homes can be saved using CFL?
Around 50-75% of energy can be saved if one uses CFL. As a matter of fact, in India, 20% of total energy consumed is for lighting purpose. i.e If the energy consumed per month is 500 units, you can roughly tell, 100 units has been consukmed for lighting purpose. Now if CFL and TFL is used, the 100 units consumed otherwise can be reduced to 50 units or even less. therefore, the effective electricity bill would be of 450 units instead of 500 units.
The SI units of electric force are?
Forces are measured in Newtons, whether they are electric or of another kind.
How many units of electricity are consumed by two HP Motor in an Hour?
1500 watt hours
How many joules of energy is consumed if the electrical meter shows 400 units of energy?
The electric meter uses kWh (kilowatt x hours) as units; a Joule is a watt x second. Therefore, a kWh has 3.6 million joules. Just multiply by this number.
How many units of electrical energy is consumed by a 3 kW stove which is switched on for 6 hours?
18kwh
Electric energy usage on your electric bill is measured how?
Electric energy is measure in Units which are kilowatt-hours. Your electricity meter records the usage in Units over the billing period. The meter measures the true power and not the volts times the amps.
How is the number of units of electricity consumed by motor in 2 hours calculated?
You can buy a volt meter, which can calculate how much electricity is passing through the wires.
Is The units of electric current is the volt?
NO! (the units of electric current is Amperes).
What is the definition of electric current the the units of electric current?
ampere
Out of 100 units of electric energy 20 of those units are used to produce light and 30 of those units are used to produce sound if the rest is converted into heat how many units of electric energy?
50 units
Out of 100 units of electric energy 20 of those units are used to produce light and 30 of those units are used to produce sound. If the rest is converted into heat how many units of electric energy ar?
50 units
What are the units for electric current?
ampere
What are the metric ruler's units?
Centimetres, with millimetres marked but not labelled.
How much energy is consumed by an 80w appliance over 1 hour?
Energy = power x time. Convert the numbers into compatible units, and multiply. If you multiply watts x seconds, the answer will be in joules. If you multiply kilowatts x hours, the answer will be in kilowatt-hours.
