Akettle transfers 2200 w of power. how much energy does it transfer in 120 seconds? also can i have your working out ; )

that power is measured in kilowatts here instead of the more usual watts. To convert from W to kW you must divide by 1,000.

For example, 2,000 W = 2,000 ÷ 1,000 = 2 kW.

Also note that time is measured in hours here, instead of the more usual seconds. To convert from seconds to hours you must divide by 3,600.

For example, 7,200 s = 7,200 ÷ 3,600 = 2 h.

A 2 kW electrical fire is switched on for 3 hours. It uses 2 × 3 = 6 kWh of electrical energy.

You also use the equation E = P × t when:

For example, a 20 W lamp lit for 100 seconds transfers 20 × 100 = 2,000 J (2 kJ).

if you answer my question i will answer yours

nah.   i'm just sleepy.
