consumption and time

[amckay]

Probably a daft question but I've just bought a new TV and want to know (out of pure curiosity) how much power it consumes per hour. It says in the manual its 69W Appliance ( 100kWh annual) but what calculation method do I use to determine its hourly consumption? The answer will prob be in my head but I suppose its just a brain fart moment!

Electric is around 11-14 pence per unit which is dependant on your personal deal. so lets say 11 pence per 1kw hour, that means if you have a one bar 1kw electic fire running for 1 hour it will cost you 11 pence. so 69 watts is more than ten times less than 1000 watts so the cost will be under 1 pence per hour, I have no calculator for the exact amount, do that your self lazy :icon10:

1 unit is 1Kw= 1000watts so your 69 watts =0.069Kw so it would run for approximately 14.492 hrs on one unit of electricity,so divide price of 1 unit by 14.492 and that gives cost per hour.

based on your 14p per unit that's 0.96p per hour.lol,where's your phone(calculator)

Cheers gentlemen. So I was right in thinking that 69w was per hour?

No, it uses 69*60*60 Joules per hour.
Careful with mixing your units!

Basically it will cost you 11-14 pence every 14 and a half hours, whether 11,12,13 or 14 pence depends on your current bill
