An electric iron is marked 20 volts 500W The units consumed by it in using it for 24 hours?

Answer 1

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.

Answer 3

The power consumption of the iron is 500W. If used for 24 hours, the total energy consumed would be 12,000 watt-hours or 12 kilowatt-hours (kWh).
